I have had my purple firefish for a little over a year now, never had issues with him until this Monday, on Sunday he was behaving normal and eating normally. On Monday he started hiding when he came out to try and eat, only to spit it out I immediately noticed a big stomach bulge and a tiny bit of what seems like white poop, but looks more like a piece of white skin coming out. He still has that coming out, and it is probably only 1 mm in length, the bulge seems to be a little smaller I think. He is coming out less and less, yesterday he ate a tiny bit, but today nothing.Was thinking it was an intestinal blockage or maybe internal worms?, I have definitely never seen him poop white. He is not looking too good, what can I do?. I have prazi pro which might do something, but also rather not dose it if it won't do anything. Catching the fish would be pretty hard but doable I think, any recommended treatments?. I have dosed prazi before - I do 7 days, then 7 days off and another 7 days, would this be the best approach?http://i66.tinypic.com/1zo85ki.png
