Upon closer examination his belly is getting hollow like the africans in the other tank. And my girlfriend reports that he does not seem interested in the jungle food.
I treated the tank again with the jungle parasite clear tabs and if that doesn't work I'll step it up to the stuff that I know is 250mg Metro/75 prazi (I even called Jungle and they were unable to tell me how much of each of those ingredients is in their tabs). 250/75 metro/prazi seemed to help the african tank, in addition to being on a jungle food-only diet. I think I may have lost one yellow lab (hard to count when so many look the same) but the peacocks bellies appear to be filling back in.
I wonder though, when it might be time to decide the metro isn't working and try to move on to something more powerful, possibly levamisole hydrochloride (not that I know where to get that). I also have Prazi-Pro that I can put in on its own too. Now that I apparently have this going on in two tanks despite all my best efforts, I really just want to be prepared for anything.
The only thing I can figure is that the snails in the hospital tank (which used to house a puffer, hence the snails' introduction) carried the parasite, and that the fish that had been in that brought the paraiste into both tanks. That's the only explanation for why they both have it but my third tank does not. I am going to empty out the hospital tank and throw out the gravel, so that it can be prepared to house this krib if he continues to ignore the food. Do I need to be worried that perhaps there is parasite living in the sponge filter of that tank? Or is that impossible?
