Too many and extra we are moving to the sump for back up supply and we have some in our other tank. We hope to keep him eating for a while! Woke up this morning and the whole tank had star fish at the top of the glass! They must have sacred “run” the harlequin is here!Got starfish I hope
Sounds like living artSpecies specific displays, done right, can be beautiful. There used to be a shop in St. Louis that had a branching hammer, all by itself, no live rock, just sand, and this giant, twisting, hammer... probably more than a hundred heads. A school of anthius were the only fishes, in a 36" square tank, fairly low. Beautiful.
I've seen a couple xenia-only tanks (or xenia-dominated) and they're actually pretty neat. I've just never had great luck wit the stuff, and I'm sure it'd just melt on me at some point.
