Fish not eating-
We have a 49 bow front tank with only four fish and live rock. The water appears to be merky, the algae is a brown/blackish color. We just found our start snail dead. I am a bit worried. PH was checked when water was changed and it was low however my fiancee added a PH chemical to it. We recently removed a fish a month ago. We are stumped.
Oh and our fishies appetites are minimal. They appear to be more aggressive as well.
Any advice would help too.
