This x pbass died this morning. I looked inside to see if I could find anything visible . I found 2 flat worm type attached by his anus. Also found a large worm attached to stomach wall. I cut the worm off the stomach and there was a orangey like jellow substance inside. I dosed with praziquantel in the water when I recieved these fish,as one of this group of fish had visible worms under skin. The affected fish got better and I thought everything was ok. Recently I have lost 2 other with also a flat worm visible inside one of them for sure. I am not real familiar with internal organs ,other than cleaning fish and removing them. So, wasnt sure about the other fish,but After seeing the same worm in this fish I can confirm it was present in the other fish . What seems to happen is the worms block the waste output and gas builds inside the fish and they die soon after .These fish exhibited loss of appetite ,then get sluggish, then next lose balance and spin to death. Tomorrow I will start to dose all my fish by putting jungle medicated food pellets in thier food . which has metronidazole,praziquantel,levamisole,in it . These appear to be two different kinds of worm . The pictures of large worm are on envelope ,and next to toothpick for flat type worm ,for size referance. Anyone have ideas on which species of worm ? Thanks for answers.
