I have a 6 line wrasse that has a HUGE belly! He is still eating and acting normal! But I know this huge belly is NOT NORMAL! Can someone tell me whatís wrong with him? He is going poop and his poop looks normal!
Since your fish are still eating and acting in a normal manner, and the only symptom is a big belly, just hold off feeding for a few days. This will allow the fish time to expell it's excess stomach content.
Your fish has an internal parasite. The white stringy poop is an indicator of such, though Iíve never seen such a massive bloat like this before.
You will need to remove the wrasse to put into a hospital tank to treat with copper based medication.
