I imagine it's probably already too late but I figured I'd try - my hector's goby (added to the tank 11/24; evo 13.5 by himself for QT) started acting strange earlier this week and then disappeared totally yesterday. He just showed back up and he's not doing well at all - he's lying in the macroalgae on his side, can't seem to swim. He is still trying though. Breathing looks pretty slow.
His colour is good, no visible parasites or mucous/discolouration. His body is pretty curved. Does this sound like anything? Is there anything I can do to help or should I go ahead and euthanize?
I added a bottle of pods yesterday and I can see a lot in there... I know this species is difficult to feed enough but I will say he was plump when I last saw him swimming about on Monday evening, not pinched or sunken like other descriptions I've seen. It was a very rapid decline.
Temp 78, no ammonia, no nitrate. It's set up like a reef tank with live rock, some sand, clump of dragon's breath algae. Tank has been set up for about a year but he's the only fish that's been in there.
Is there anything I can try? Or at least, does this sound like anything so I know what might have happened/avoid it with another fish?
