These are wee little guys. One is about 1" and the other about 2.5". The little guy has gone and attached to some sand grains. He sits in a piece of lime rock (dry live rock I bought at Big Als) that I chiseled out a small depression in for him to sit in.
The larger one appears to have no interest in attaching to anything. I am trying to find it divets in the rock. If I put it in too high a flow area then it just gets blown over. So I try to find medium to low flow areas and generally speaking lower down in the rockwork because the higher you go the more flow/water velocity.
Both are the golden or brown varieties. I can't bring myself to try a blue or green guy for more $$$ when all I have is bad luck with them.
Sigh ... I don't know what I'm doing wrong.
