Yes Corey, there's a decent chance your ocellaris will take to your GBTA. And, you mentioned you have a bare tank. BTAs are rock dwellers and never dig in the sand, so you're good there. Not sure what you're referring to when you ask "should they be on the same side of the tank?"
Sorry OP if this side note appears to be highjacking, I just wanted to answer Corey's questions.
