Well I cannot use salt because of my loaches. I need to figure out what is causing the dropsy I think since this is the 3 rd fish who has done this in about 3 weeks.

Hello. I have a mixed tropical tank. Water parameters are all good. Ph a little high at 7.8. But steady. I had mollie die a few weeks ago, then a dwarf Gourami got sick could  not stay upright swimming and quit eating. Put him in breeding box and he finally died. Nothing wrong when looking at him. Now i have a larg Buenos aires tetra that did same thing and kind of pine conning and tail is rotted looking. But she looks very bloated. Curious if you have any idea what could be going on.   Leaning towards internal paracite. Please mote I do have clown loach in the tank, and its a 60 gal tank.
