I have a 25 gal with live rock and this set up was purchased by my wife as a gift. A gift that was in trouble when I came home with it set up. I have only a 1 1/2 inch Skunk Clown Had 1 purple Psuedo and 2 green chromis .The Chromis died before I got home to see gift. I purchased 4 Chromis last week they were dead two days later they were very small Clown was picking at them never found any of the dead fish. We think He killed them but not shure. Can't get Clown out of tank unless i tear all rock out he hides. What can I put in with him?
