Big Belly Trigger

[fish fever]

My Humu trigger has a BIG belly! He looks very bloated. He is about 1.5 inches. He is in a 95g tank with 3 chromis, a valentini puffer, a yellowtail wrasse. All of them are small, between 1 to 3 inches. My water parameters:
temp 78.5
pH 8.2
Amonnia 0
Nitrite 0
Nitrate 0
All fish look very healthy and eat a lot. I feed them 2 - 3 times a day.

imo i would say you need to cut down on the feeding just a little bit

is it possible an internal parasite problem? I only feed them 1 cube of mysis shrimp per day, half a cube each time.
