Wow, you've just read my mind...I'm thinking of getting one. My only issue is I have an open top look and wouldn't want anything bulky hanging on the tank.
Welp, I'm down to 3 chromis' now. The other two literally disappeared into the rocks yesterday, never to be seen again. They were acting lethargic for some reason, even when I fed the tank, they'd just swim in one place. And those were the two that paired up and never swan with the school.
Yea it'll take Him a couple days to completely overturn the sand but once he does it'll clear up. Did he build his burrow yet? It's quite comical. His is right in front of the glass so I cover it and he gets all pissed at me. He takes a mouth of sand and spits it out at me
