Jello Sr has not been feeding for a few months and has been retaining an increasing amount of fluid. IDK what's wrong.
I can't vouch for it but the problem might have started about 3 years ago when she had eaten and then regurgitated hours later a 10" tilapia from our outdoor ponds. The tilapia had been, however, properly frozen to kill off any parasites before being fed to the catfish. It wasn't the first time or the last we fed our raised tilapia, mayan, jewel, etc. to our fish and we never had any other obvious problems, but Jello Sr seemed to have not been the same ever since. She has been feeding overall 10x less ever since and took long periods of not feeding at all.
This is the first round of 3 of a general antiparasitic treatment of metro+prazi:
