Lumpy belly - Bicolor Blenny

[trinac]

By feeding the pellets only, which he still hasn't figured out are food, his belly has decreased notably. Still bumpy though, as the blenny is often foraging on something. I'd have to isolate him and remove food completely if I really want to rule out that the blenny just eats too much.

My book came in the mail today (Health & Feeding Handbook). From what I can gather, the alternative is that it is some kind of sporozoan. I will just have to monitor the situation. If it does get worse, I'll have to isolate the fish and likely euthanize as sporozoans, if cysts rupture, can infect other fish. Also, no known cures / effective treatments.
