I had 4 different types of percula clown fish and an 8" engineer goby in my 72 gallon tank. A friend was selling a group of 5 chromis he had for a year. after QT, they were added in. there is one fairly large chromis (bigger than my female perc). The clown fish juveniles hide by the return nozzle and rock tower on the right, where the 5 chromis cruise the tank. The smallest picasso has disappeared and nocorpse to be found. I ripped out my sand bed this past weekend and no bones, no nothing.... it's a mystery:eek:
