I had a small colony of zoas and a lobo I put in another tank he liked those. I have a few sps colonies I figured he would like and he does but I am ok with that. I care about my torch hammer and frog. he has not looked at those he really likes one bright green acro colony I have you can see it in the backround of the last picture. I may have to set up another tank for my torches etcc If he likes those I really like leathers and they do not eat those so I will be adding a bunch of those
