Damsels in distress
We've had our aquarium set up since mid May. During the cycling process we lost two yellow-tailed damsels, two clown fish and one scooter blenny (I know, since then I have learned I should not have used fish for cycling); one scooter blenny survived and is doing great. The tank finally finished cycling, everything was down to 0, pH 8.2 and salinity 1.020. We got two domino-damsels on September 2 and they seemed to be doing great; on Monday morning (September 6) one was dead, no signs or symptoms the night before. The other died today (September 8), but hadn't been right since the first one died. All the readings are still at zero, pH 8.2, salinity 1.020, the scooter blenny is fine; what went wrong? I am now VERY reluctant to get any new fish. Do you have any ideas or suggestions?
Tank is 55 gallon, sand (not live) on the bottom, two coral skeletons, one artificial decoration. I have been feeding frozen brine shrimp. I would really appreciate some help on this. Thanks in advance.[/i]
