No more for me they really become a problem (aiptasia) when your tank and Parameters are good. maybe if I do clownfish tank but in have trouble getting these guys out
I had a Colorado Sunbust BTA and would 100% get one again. It moved around quite a bit, but it didn't bother anything in my 20g. It was a stunning centerpiece in my reef.
I would, but only after making sure I have precautions in place to get the inevitable splits out of the tank quickly. They're great for movement within the tank and clowns love them, but left unchecked they can be just as overwhelming as xenia or GSP.
