BW, clearly I have a different species or maybe this takes many months to happen ?
I've had them since June and they are never on the rock. Do you pellet feed your tank?
I have 5 or 6 different mushroom species, gsp, gorgonian, etc. that they've never touched. I can understand the xenia, as pretty much everything I own eats that weed, thank goodness.
I guess we'll see what happens in the long run. Thanks for the info.
