I wanted a traditionally colored weather loach to keep my two golden dojos company. I went to my local lfs, and the loaches were in horrible condition. mostly eaten, fin and tail rot, and goodness knows what else. terrorized. there were three that had even a chance of making it, the rest weren't going to make it. i took all three (yes, i know how big they are, and if i can't upgrade my tank when i need to, i have friends who are willing to take them and give them happy loachey homes), i couldn't just leave them there to be chowed by the cichlids they were being housed with. 2 were about 2 inches each, one was about 2.5. all scary thin. this was saturday. they're in a 2.5 hospital tank (yes, i know that's too small, it's just for a couple of weeks, long enough for anything else they have to present before i throw them in with everybody else). one died yesterday, the smallest, thinnest, least active. they have an airstone, a 5g filter, doing 50% daily water changes, and i'm treating them with melafix (i was told that this is easier on loaches, as they dont have scales, and regular antibiotics are too harsh for them). the biggest one has taken one bite of one algae wafer, and the other nibbled goldfish flake once, but otherwise, they won't eat (i've offered sinking carnivore disks, goldfish flake, tropical flake, and peas). i know fin healing takes time, but they seem worse rather than better. any treatment/food suggestions would be more than welcome.
