I got three albino corydoras from Petsmart a week or so ago, and two have since died, both times while I was gone for a day. I come back to find a pale and dead fish and quickly scoop it out.
I've never seen any of the three eat, though I bought some sinking pellets and kept an eye on them throughout the day. Their only tankmate, a platy, seems to eat them more than they do.
The tank is cycled and has zero ammonia/nitrite. I'm good about water changes and nitrate is typically under 30. pH is around 7.8. The tank is ten gallons, at ~76 degrees. I vacuum the gravel about once a week.
When I bought them at Petsmart there was a dead cory in the tank -- is it possible or likely that they got a disease from the dead one and have spread it? The two that died were the most inactive ones -- they would hang around the bottom of the tank for hours on end and only move around once in a while. The remaining one swims around a lot.
I know I need more cories to keep him company, but I want to figure out why they're dying first.
