So I noticed my blenny occasionally has a very bloated stomach, I'm not sure if it is related to this bubble he has on his fin, the bubble has gotten smaller so I took him out of QT but now seeing this inflamed stomach I'm not sure what I should do. It doesn't look like this all the time, but it becoming more frequent, none of my other fish look like this, will attach photos below. He eats very well, haven't noticed any odd behavior or stringy poop. Anything helps! thanks!
