Hi all brothers,
Need your advise.
I have this 2.5' tank, which has been stablized and the fishes are happily stay and everything was alright.... 2 days ago, my coral beauty & one blue trigger died. Then, this morning my lemon peer also follow them. Why? I checked thru their bodies, there isn't any trace of wound.... My anemone is doing fine, the rest of fishes are still happily living there..... What could goes wrong? Any advise?
