3 1/2"... Eats brine or mysis flakes and pellets... Twice a day. Have clowns, tangs, CHROMIS, Midas BLENNY and wrasse. Good with all... Haven't had aipstasia since. Want to get back into zoas but it's trying to eat them. So ready to pass it on.
Me too I like the way it looks prehistoric..ive thought of just putting in and then keeping in my sump....once he cleans house....if he is well feed he may not touch zoa....
