Lumpy belly - Bicolor Blenny

[trinac]

Hello

My Bicolor Blenny has a lumpy belly. It looks intestinal like, either wormy or bloated from eating too much? The portion that is lumpy is just beyond his front fins to about 50mm back. He's eating algae off of the glass, rocks, etc, and eats some mysis. Hasn't yet been interested in the pellets. His poop is greeny / brown and what I can best describe as solid, its not stringy or anything. Any ideas on if this is something to be treated, or if he's just pigging out bigtime? I have a book on the way about fish diseases... but it hasn't arrived yet!

Your help is appreciated!

If there is any additional information you would like to know, please ask. I am running the gamet of water tests today. Previous test history is normal and good. Last nitrate was between zero and 1. Ammonia & nitrate always zero, although I do need to upgrade those test kits (API).

Thanks!!
