About
Tucked back off Morris Avenue in Union, NJ, Discus Madness is a freshwater fish store that genuinely earns its name. The showroom runs something like 400 tanks, and regulars describe walking in to find them pristine — clear glass, spotless water, and fish that, as more than one visitor puts it, seem to glow. The discus are the headline act: an enormous, ever-rotating wall of strains and sizes, from deep red turquoise to smokey white butterfly, that collectors drive an hour or more just to browse.
As one shopper from the Philadelphia area put it, even the non-discus selection far surpasses anything in his area, and it's not close. Beyond discus, this is one of the most serious freshwater rooms in the state. Angelfish for sale in Union, NJ have their own following — one customer is still kicking herself for taking home just a single stunning red angel instead of two.
The store has quietly become a pleco destination too, stocking everything from basic bristlenose to coveted rarities like Zebra plecos (L046), sunshine plecos, and L600s. You'll also find tetras, healthy corydoras, a deep supporting cast of tropical community fish, and racks of live aquarium plants, plus the tanks, equipment, and supplies to put a build together. What keeps people coming back is the staff.
Danny earns repeated shout-outs for steady, no-nonsense advice; Rebecca will sit with you to map out a discus tank; and Mathias once helped a customer pull off an entire Skittles-themed build. They quarantine incoming fish and stand behind a deceased-fish policy — reassuring when you're spending real money on livestock. Prices come up again and again as fair for the quality.
If you're hunting for discus for sale near me in northern New Jersey, this Union showroom is, by wide local consensus, the best around.
