i thought crocea and maximas like to be in the rockwork as they like to burrow?
i remember reading somewhere that even if you keep in the sandbed, you should give it a solid rockwork underneath to securely attach..
hiep, i think if you have strong enough pc's and keep clam way at the top you could be okay, what lighting are you running? hope things are going well, thanks again for the frags and shrimp..
