I just bought my first fish for a freshly cycled tank yesterday. 3 blue/green chromis. I let them acclimate, then released them into the tank. Immediately, all three hid behind the rocks (normal...), but when they decided to come out around 30 minutes later, only two came out. There is nothing in my tank, aside from live rock and a few critters that came with it, that I think could get the third fish. I tried moving around a couple rocks to get a better look, but it seems to have completely disappeared. Is this normal? I can't seem to figure this one out... :question:
Thanks!
Thanks!
