This is a very nice piece... and very LARGE piece Sergio... Thanks! It has acclimated well. Sunday night I was feeding all my chalices just after lights out and I was AMAZED at the lenth of the sweeper tenticles on this guy. All my chalices have 1/8" to 1/2" tenticles they put out when they feed but this guy was putting out 2 1/2" + tenticles all over the place! I went ahead and moved a couple of other chalices I had near by just in case. Have you had any experience with this guy harming neighboring corals? Is 2"-3" normal for this one or can I expect longer?
