Hi all. Against my better judgement, I purchased six Sterbai cories at a fish store that seems to have a lot of quarantined tanks. I'm used to my fish getting Ich almost every time I add new fish, but this time, I'm really not sure what's going on.

Within days of purchasing the cories, one of the smaller catfish died (he had lost all his color and was floating at the top). Then, a few days later, another catfish became so listless and emaciated, I had to euthanize him. Around that same time, one of my marble hatchets went missing (found him dead when I cleaned my tank).

Symptoms mainly include flashing and darting around in a crazy/irratic way--expecially when finding food pellets at the bottom. As the illness progresses, they stop eating, become listless, or keep swimming to the top of the tank, either resting on top leaves of plants or constantly taking gulps of air.

I treated the tank with Tetra Parasite Guard--two doses over a four-day period with a water change and they seemed to be doing better, but I just noticed the larger of the four remaining cories flashing again and one of the smaller ones doesn't seem to be eating, but instead spending it's time at the top of the tank.

Should I do another round or two of the Tetra Parasite Guard or try something else? The instructions do say that if it's flukes or mites to treat again the following week. But if I can't SEE what it is, then how am I supposed to know? I did notice one of the smaller catfish looked like he had a hole in his head, but he's so small and quick--plus Sterbais DO have spots--I'm not positive.

I have a planted tank that I just re-landscaped yesterday and don't want to use anything that would harm them.

Any suggestions?!
 
Sounds similar to the things I am seeing in my tank. I am treating with a medicated food for internal parasites. I don't think treating the water does much for the internal ones.

I am using paracide-x, but may try Metronidazole powder is the first doesn't work. I know seachem makes a metro powder.
 
Thanks. It's very frustrating dealing with these illnesses--I feel like I'm constantly dumping hazardous waste into the tank to get rid of them. I wish I had a hospital tank--would certainly make things easier.

I think I'm going to try another round of the Tetra Parasite Guard, since it does state to do that for particularly difficult to treat parasites--and it also treats internal parasites. If after another round, I'll try something else. I just really hope the second round does it!
 
good luck! I hate this part too. Hospital tank didn't help me because I added a big group of fish after a fishless cycle and the whole tank was contaminated :crazy:

Really feels unfair that other people buy perfectly healthy fish.

Hope your fish heal soon, it's very upsetting.
