Neon/Sharknose goby lifespan??

[christyf5]

Well if he had found another food source he wouldn't be looking so.... well I'd call it a bit better than emaciated. Basically his head is bigger than his trunk. I like my fish (especially gobies) to be fuller throughout that area and he is looking much less "healthy" (read: less of a fatarse) than he used to. Thing is I can't even get him looking full by feeding him as he stops eating after about 4-5 tiny food pieces. Perhaps I should investigate finding a some new food. Maybe he's tired of what I feed (sweetwater zooplankton, mysis and Faunamarin UltraHealth).

Could be he's just moody because he doesn't have a girlfriend I see he's cozying up to my lined blenny lately. "hey baby, come here often?"
