Learn about Hasemania nana tank requirements, their unique 'no-adipose fin' anatomy, and how to manage their active behavior. ## Species Overview The Silver Tip Tetra (*Hasemania nana*) is one of those species that looks ordinary in a store tank and electric in a planted aquarium. A burnished copper body, three crisp white "silver tips" on the dorsal, anal, and caudal fins, and a darting, restless swim pattern that immediately catches the eye. They are not flashy in the way a neon or a cardinal is, but in a school of ten or more under warm lighting they put on one of the more underrated displays in the freshwater hobby. Silver Tips are also one of the few small tetras that lack an adipose fin — that small, fleshy lobe between the dorsal and tail that defines most of the family. The genus name *Hasemania* literally references this missing fin. It is a small detail that throws off beginners trying to identify them and a useful diagnostic for anyone shopping a mixed tetra tank at a local store. | Field | Value | | ----------- | ---------------------------- | | Adult size | 1.5–2 in (4–5 cm) | | Lifespan | 5–8 years | | Min tank | 20 gallons (school of 6+) | | Temperament | Semi-aggressive (fin nipper) | | Difficulty | Beginner | | Diet | Omnivore | > **Silver-tipped fins on a copper body** > > The defining mark of a healthy Silver Tip is the contrast — a burnt-orange or coppery body finished with three sharp, opaque-white tips on the dorsal, anal, and caudal fins. Pale, washed-out fish in a store tank are not a different morph; they are stressed or kept in too-small a school. A well-kept male in a planted tank looks like a small piece of polished metal with white-painted fin tips. ### Identifying *Hasemania nana*: The Missing Adipose Fin Look at any other small tetra — neon, cardinal, ember, rummy-nose — and you will see a tiny rayless fin sitting just behind the dorsal. Silver Tips don't have it. That single feature is the easiest way to confirm the species in a store tank where labels have been swapped or misprinted. Beyond the missing adipose, the body is laterally compressed, deep-bellied, and ranges from a soft yellow-silver in females to a deep copper or burnt orange in dominant males. The white fin tips are present in both sexes but appear more vivid against the darker male body. ### Natural Habitat: The Copper-Colored Waters of Brazil In the wild, Silver Tip Tetras inhabit the slow-moving tributaries of the São Francisco River basin in eastern Brazil. The water is soft, gently acidic, and often stained the color of weak tea by tannins from leaf litter and submerged wood. Sunlight filters through overhanging vegetation, leaving the water column dim and the substrate dark. You don't need to recreate a full blackwater biotope to keep them happy, but a planted tank with darker substrate, some driftwood, and a few floating plants to dim the surface produces the most natural behavior and the deepest copper coloration. ### Lifespan and Maximum Size Adults max out around 1.5 to 2 inches, with females running slightly larger and rounder. In a stable, well-fed tank they typically live 5 to 8 years. Stress from undersized schools, chronic nitrate buildup, or repeated temperature swings shortens that figure considerably — color fades first, immune function follows. ## Water Parameters & Tank Requirements Silver Tips are forgiving across a wide chemistry range, which is a major reason they earn the beginner label. Stability and school size matter far more than chasing exact numbers. ### Ideal Temperature (72°F-82°F) and pH (6.0-8.0) Keep the tank between 72°F and 82°F, with the sweet spot sitting around 75-78°F for sustained activity and color. They tolerate a pH from 6.0 to 8.0, though they color up and behave most naturally in slightly acidic to neutral water (6.0-7.2) that mirrors their native São Francisco habitat. Hardness should sit in the 5-20 dGH range. A reliable heater rated for your tank volume is non-negotiable. Verify with a separate thermometer — built-in heater dials drift over time, and a 6°F overnight swing is enough to crack the door open for ich. ### Minimum Tank Size: Why 20 Gallons Is Better Than 10 for Swimmers Silver Tips are constant, fast swimmers. They patrol the middle and upper water column non-stop, and they need horizontal length to do it without crashing into glass. A 10-gallon tank can technically house a small school, but the behavior you'll see in a 10 is twitchy, claustrophobic, and prone to in-school aggression. Twenty gallons (a standard 24-inch long tank) is the practical minimum for a healthy school of six to eight. If you want the calmer, more dispersed behavior of a school of ten or more — which is also the school size that most reliably tames their nipping reputation — step up to 29 or 30 gallons. See our [20-gallon fish tank guide](/guides/20-gallon-fish-tank) for stocking and equipment notes. ### Lighting and Substrate to Enhance Copper Coloration Bright white sand and intense overhead lighting wash Silver Tips out. They look like pale yellow shadows of themselves under those conditions. Dark substrate — black sand, natural dark gravel, or a planted-tank aquasoil — combined with moderate lighting and some floating plant cover produces a dramatic shift in coloration within days. A standard hang-on-back filter rated for your tank size handles biological load without producing the heavy current Silver Tips dislike. Aim for gentle to moderate flow. Add a few pieces of driftwood and some Indian almond leaves if you want to deepen the amber tint of the water — both encourage the warmest copper tones in dominant males. ## Diet & Feeding Silver Tips are unfussy omnivores with healthy appetites. They will hit the surface within seconds of a feeding and chase down anything that drifts past in the water column. ### High-Protein Flakes and Micro-Pellets A quality flake or micro-pellet rotation forms the dietary backbone. Look for foods with named protein sources (krill, salmon, fish meal) at the top of the ingredient list. New Life Spectrum, Hikari Micro Pellets, and Omega One Color Flakes are reliable staples. Feed a small pinch one or two times daily, only as much as the school clears in 60 to 90 seconds. Rotating between two or three different dry foods covers nutritional gaps that any single product would leave. Color-enhancing varieties with astaxanthin and spirulina deepen the copper tones over a few weeks. ### Importance of Frozen and Live Foods (Brine Shrimp and Daphnia) Two or three times a week, swap dry food for frozen bloodworms, brine shrimp, daphnia, or mysis. These trigger natural foraging behavior, fuel the brightest coloration, and condition adults for spawning. Silver Tips will hunt live brine shrimp with visible enthusiasm — it is one of the more entertaining feedings in the freshwater hobby. Live blackworms or microworms are excellent occasional treats but carry some disease risk if sourced from unknown suppliers. Stick to reputable culture sources or freeze-dried alternatives if you are unsure. ## Tank Mates & Compatibility This is where Silver Tip ownership goes either smoothly or sideways. Their reputation for nipping is real but entirely manageable with the right approach. > **Schooling 6+ minimum — 10 is the real number** > > A school of fewer than six Silver Tips is the single biggest reason their nipping ends up directed at other species. In small groups they have no internal hierarchy to occupy them, so they take their excess energy out on whatever else is in the tank. Six is the absolute floor; ten or more genuinely changes their behavior by giving the dominant fish proper rivals to chase within their own school. ### The "Magic Number": Keeping Schools of 6-10 to Reduce Aggression Silver Tips are wired for schooling behavior. In a proper group of ten or more, the dominant male establishes a pecking order with other males and burns off energy through harmless intra-school chasing. In a group of three or four, that same energy gets directed at slower tank mates because there are not enough peers to absorb it. A school of fifteen Silver Tips in a 29-gallon tank is shockingly peaceful toward outsiders compared to a school of four in the same tank. This is the single most actionable lever you have for behavior management — buy more fish, not fewer. ### Best Companions: Corydoras, Rasboras, and Robust Tetras Pair Silver Tips with fish that are either too quick to nip or too unbothered to care. Solid options: - Corydoras catfish (peppered, bronze, sterbai) — bottom-dwelling and short-finned, totally ignored by Silver Tips - Harlequin rasboras and lambchop rasboras — fast midwater swimmers with no flowing fins to target - Black skirt tetras, [black phantom tetras](/species/black-phantom-tetra), and other robust tetras of similar size - Otocinclus and bristlenose plecos — algae eaters that ignore midwater drama - Zebra danios and pearl danios — too quick to be caught - [Neon Tetras](/species/neon-tetra) and rummy-nose tetras when the Silver Tip school is genuinely large (10+) and the tank is well-planted For a fellow nippy tetra to compare temperament, see the [Serpae Tetra care guide](/species/serpae-tetra). For a broader compatibility overview, our [freshwater fish guide](/guides/freshwater-fish) covers community stocking from the ground up. ### Species to Avoid: Long-Finned Slow Movers (Angelfish and Bettas) > **Fin-nipper risk with long-finned tank mates** > > Never combine Silver Tip Tetras with bettas, angelfish, fancy guppies, gouramis, or any other slow-moving long-finned species. Those flowing fins act like bait — even a well-schooled group of Silver Tips will drift over and start picking at them within a day or two. The damage is rarely lethal on its own but creates entry points for fungal and bacterial infections that often are. Specific species to keep out of any tank with Silver Tips: - Bettas — long flowing fins, slow swimmer, will be shredded - Angelfish — long ventral fins hang down like targets - Fancy guppies — flowing tails, slow movement - Gouramis (especially pearl and dwarf) — long pelvic feelers and slow grace - Fancy goldfish — wrong temperature anyway, but long fins seal the issue - Long-finned bristlenose plecos — usually fine in body but long fins get nipped ## Breeding the Silver Tip Tetra Silver Tips breed reliably in the home aquarium given the right setup, though they make poor parents and will eat their own eggs within minutes if left in the spawning tank. ### Distinguishing Males (Copper) from Females (Pale Yellow) Sexing Silver Tips becomes obvious once they hit adult size. Males display a deep, saturated copper or burnt-orange body and slimmer profile. Females are noticeably paler — a dull yellow or silver tone — with a rounder, deeper belly that becomes pronounced when conditioned for spawning. Both sexes carry the white fin tips, but they read more vividly on the darker male body. ### Setting Up a Spawning Mop or Moss-Bottom Breeding Tank Use a separate 10-gallon breeding tank with soft, slightly acidic water (pH 6.0-6.5, dGH under 8), a temperature of 78-80°F, dim lighting, and a thick mat of Java moss or a fine spawning mop on the bottom. Condition a small group of two males and three to four females on live and frozen foods for a week before introducing them. Drop the conditioned group into the breeding tank in the evening. Spawning typically occurs at first light, with eggs scattered across the moss or mop. Remove all adults immediately afterward — they will hunt down and eat the eggs otherwise. ### Raising Fry: Infusoria and Baby Brine Shrimp Eggs hatch in 24 to 36 hours. Fry consume their yolk sac over the next three to four days, then need infusoria, commercial liquid fry food, or vinegar eels for the first 7 to 10 days. Switch to newly hatched baby brine shrimp once they are large enough to take it. Daily small water changes with matched-temperature water keep the fry healthy and growing. ## Common Health Issues Silver Tips are hardy by tetra standards, but they are still susceptible to the standard freshwater disease lineup. Catch problems early and most are easily treated. ### Ich and Velvet: Prevention Through Quarantine Ich (*Ichthyophthirius multifiliis*) shows up as small white grains scattered across the body and fins, almost always following a temperature drop or the introduction of a new fish. Treat by raising the tank temperature to 82-84°F for 10-14 days and dosing a quality ich medication if the parasite persists. Velvet (*Oodinium*) is a more dangerous flagellate that produces a fine gold-or-rust dust coating on the skin and gills. It progresses faster than ich and is harder to treat — copper-based medications in a quarantine tank are the standard approach. Both diseases are entirely preventable with a 2-3 week quarantine of every new fish before adding to the display tank. ### Stress-Induced Nipping and Fin Rot Frayed or torn fins on a Silver Tip almost always trace back to one of two causes: in-school aggression because the group is too small, or external aggression from a more dominant tank mate. Damaged fins are vulnerable to bacterial fin rot, which appears as ragged white edges that progress inward toward the body. Treat the underlying behavioral cause first — increase the school size, remove the bully, or rehome incompatible long-finned species. Then treat any active fin rot with a quality antibacterial medication and clean water. Color loss is the early warning sign; pale, gray, or washed-out fish are stressed fish, and stress is what opens the door to disease. ## Where to Buy & What to Look For Healthy stock from a reputable store is half the battle. Stressed, washed-out fish from a chain pet store often arrive with parasites and recover slowly if at all. > **Sometimes labeled 'copper tetra' at the LFS** > > Silver Tip Tetras occasionally get sold under the alternate name "copper tetra" — both refer to the same species, *Hasemania nana*. Check the scientific name on the tank label or ask staff if you are unsure. The missing adipose fin is the easiest in-tank confirmation; if the fish has a small fleshy lobe between the dorsal and tail, it is not a Silver Tip. ### Assessing "Silver Tips" for Vibrancy and Fin Integrity Inspect any Silver Tip carefully before buying. Look for: - Clear, sharp white tips on the dorsal, anal, and caudal fins — washed-out or tea-stained tips suggest stress or poor health - Saturated copper coloration in males, healthy yellow-silver in females — pale gray or whitish bodies are warning signs - Active swimming in the upper two-thirds of the tank, not hiding in corners or hanging at the surface - Intact fins with no tears, white edges, or fuzzy growths - Clear eyes and a flat (not sunken, not bloated) belly profile - Visible feeding response — ask staff to drop food and watch which fish eat Check the tank itself. Dead or visibly sick fish in the same system mean the entire batch is suspect. A clean tank with active, eating fish is the only acceptable starting point. ### Why Local Fish Stores Offer Better Schooling Stock Than Big-Box Chains Big-box chains rotate stock quickly and often house Silver Tips in mixed tetra tanks where they are stressed, under-schooled, and visibly washed out. A good local fish store keeps them in a properly sized school, often with dimmer lighting and darker substrate, which makes assessing health far easier. A reputable LFS will also let you watch the fish feed before you commit, will know roughly when the shipment arrived, and can usually tell you whether the fish are wild-caught or commercially bred (most modern Silver Tips are tank-bred in Southeast Asia). Buy six to ten at once — splitting purchases across multiple trips is what produces the under-schooled aggression that gives this species its bad reputation. For a typical Silver Tip community setup, plan a 20-gallon tank with at least eight individuals, ideally ten or more. Pair with corydoras and harlequin rasboras for a balanced, easy-to-maintain community. ## Quick Reference - **Tank size:** 20 gallons minimum for a school of 6-8; 29+ gallons for 10 or more - **Temperature:** 72-82°F (sweet spot 75-78°F) - **pH:** 6.0-8.0 (best at 6.0-7.2) - **Hardness:** 5-20 dGH - **Diet:** Omnivore — quality flakes/micro-pellets, frozen bloodworms, brine shrimp, daphnia - **Schooling:** 6 minimum, 10+ ideal to control fin nipping - **Tankmates:** Corydoras, harlequin rasboras, black skirt tetras, danios, otocinclus - **Avoid:** Bettas, angelfish, fancy guppies, gouramis, any long-finned slow swimmer - **Difficulty:** Beginner (with the right tank mates and school size) - **Lifespan:** 5-8 years ## Frequently Asked Questions ### Are Silver Tip Tetras aggressive? They are not aggressive but are highly energetic and "nippy." This behavior is most common when they are kept in groups smaller than six. In a proper school of 10 or more, they focus their energy on each other rather than other species. ### How can you tell a male Silver Tip Tetra from a female? Males are significantly more colorful, displaying a deep copper or burnt-orange body. Females are much paler, usually a dull yellow or silver, and have a rounder belly, especially when carrying eggs. ### Do Silver Tip Tetras need a heater? Yes. As tropical fish from Brazil, they require stable temperatures between 72°F and 82°F. Fluctuations can weaken their immune system, making them susceptible to Ich. ### Why is my Silver Tip Tetra losing its color? This is usually due to stress, poor water quality, or lack of darkness. They often "pale out" at night when the lights are off. If they stay pale, check your ammonia and nitrate levels immediately. ### Can Silver Tip Tetras live with shrimp? It is risky. While they won't eat adult Amano shrimp, they will actively hunt Neocaridina (Cherry Shrimp) shrimplets. If keeping them together, provide dense moss cover for the shrimp to hide. --- *Source: [FishStores.org](https://www.fishstores.org/species/silver-tip-tetra)* *Last updated: April 24, 2026*
