Woke up and the filers were off and 3 of my original fish were dead. Lost my sailfin, clarki and coral beauty. Had them all about 7 years ugh anyways that being said. Wanting to replace them but all the a--hole fish reappeared after about an hour of filtration. Tank load is 3 pajama cardinals 1 pipefish 1 neon dottyback 1 mandarin 1 pink spotted goby and 2 damsels yellow and blue. Any suggestions on new tankmates?
