Bummer. I am guessing that the problem with my cories is most likely bad stock then, too?
My fish:
Bought 6 habrosus cories from the LFS. The two smallest are very quiet, mostly just lay on the bottom, not very active. I know the LFS had them for almost a week before I bought them. I drip-acclimated them over 2 hours, although they did get some temperature shock because I didn't realize I overheated the bucket they were in about 8 degrees warmer than the tank. (oops!) My water was all zero for nitrites, nitrates, and ammonia when I tested. The water should be similar to the LFS because I know they use 50% tap 50% RO and that's what I do too. I've had them for 5 days now. Four are doing great, but two prefer to imitate gravel than act like cories
