I realized that one of my jacks was sick after feeding live blackworms so i put him in a different tank and medicated it with Jungle parasite clear. Its been almost a week and my JD still looks terrible, is listless and wont eat, but he is not breathing really hard anymore. I read somewhere that some fish just get sick from eating too many blackworms at once, could this be possible?? The 10 other fish in the tank with him are all healthy! Anyway i can get my fish to eat? or any recommendations on medications i can buy at my LFS that might help?
