The owner's dedication shows in a detail that experienced fishkeepers will immediately appreciate: every tank in the shop runs on an individual filtration system rather than a shared sump, meaning disease and parasites can't hop from one stock tank to the next. It's a labor-intensive choice that speaks volumes about the priority placed on livestock health. The freshwater selection punches well above what you'd expect from the store's compact footprint. Guppies are a particular standout — the owner has imported strains never before available in the US, and multiple reviewers single them out as the finest in the state. German Blue Rams, peacock gudgeons, bettas with vivid coloring, and a rotating cast of exotic and rare species fill the rows of clean tanks. Hardscape materials like stone and driftwood line the shelves for anyone planning an aquascape, and you can pick up blackworms, fish food, and general supplies without needing to order online. Customers regularly drive from Green Bay and beyond to browse the stock, and Fish Cave also ships — one reviewer ordered guppies and had them shipped the next day. The store supports the Milwaukee Aquarium Society, reinforcing its roots in the broader Wisconsin fishkeeping community. The space is admittedly snug, and parking in the winter can be tricky given the oddly shaped lot, but most visitors find the density of the selection a feature rather than a flaw. If you have a specific species in mind, the owner is happy to source it. Staff — often the owner's family — are consistently described as patient and genuinely eager to talk fish, whether you're setting up a micro tank or hunting for something nobody else in Appleton carries. It's a family operation built on passion, and repeat visitors keep coming back because the fish arrive home healthy and stay that way. ## Specializations - **Water Types**: Freshwater - **Livestock & Products**: Rare Species, Bettas, Livebearers, Shrimp, Invertebrates, Dry Goods, Fish Food - **Services**: Ships Fish, Consultation - **Known For**: Premium Equipment, Knowledgeable Staff, Healthy Fish ## Highlights - Individual filtration on every tank prevents cross-contamination between stock - Imported guppy strains unavailable anywhere else in the US - Ships fish — orders fulfilled next day - Wide selection of rare and exotic freshwater species in a compact space - Hardscape materials, blackworms, and fish food available on-site ## Customer Reviews **"Dan Owen"** - 4/5 - Edited a month ago > They have many kinds of fish for sale and the tanks look very clean, too. They also have fish food and supplies. **"Ethan Johnson"** - 1/5 - a month ago > I am truly disgusted, and disappointed in my visit. Walking in I was attacked with the smell of a rotten animal, I thought maybe someone who came in here just maybe smelt bad. But no. (usually fish stores have a scent and I won’t deny that, but this smell made me walk out gagging) walking around I noticed that some fish looked amazing, while others were not so lucky. there was one specific tank that was full. I mean full of dead and decaying fish. the water was cloudy and I believe that was the cause of the smell. Also noticed that the prices were high, I don’t mind paying extra for some good quality fish, but when there’s dead fish everywhere it turns you down. I also understand that dead fish is the nature of the hobby, but not tanks full of fish that might have been there for weeks. **"Randy Schilling"** - 5/5 - a month ago > Very cool store. Very clean. And a lot of unique fish **"Alex Casey"** - 5/5 - a month ago > This store is truly amazing, ALL the difference selection of fish is just Great. Extremely Friendly as well as Knowledgeable.
