Hello guys ! New to the site and this is my second time in trying out a fish hobby. Don't know what's going on here but I have a biocube 29(new model) set up for about two months now. I let my tank cycle for about two weeks wi around 30 lps
of live rock, sand with snails and crabs coming in around week 1-2. Then started getting fish with the first two being a clown and some sort of long blue skinny fish with a yellow stripe. After about three days they started fighting a lot so I got to return them and got a carpenter fairy wrasse along with my fav a green spotted mandarin. I've had them both around a month now and can't ever get the wrasse to come out. I was told to try and add another wrasse and got a flasher wrasse. The carpenter won't come out. Not even during feeding time. The other two are very active while the carpenter just hides under rock in the very back. I maintain water changes frequently and everything else seems fine. What's going on?
