Bronze corydoras tank mates
The cory most beginners buy. Tolerates a wider pH, temperature, and hardness range than almost any other cory. A solid first bottom-dweller for a community tank, given six fish on smooth substrate.
Common mistakeBuying three bronze cories for a community expecting a school is how keepers invent shy, stressed bottom fish that hide all day. Six is the real start. Add the full group at once on soft sand — token trios never behave like the species you watched on video.
