What's your opinion on them?

I have a TON in my tank. They don't bother any of my corals. I view them as a beneficial part of the CUC. Some say that they eat coraline algae or corals, especially if they are a darker color.

I would start removing them. I have some that think high end zoas are tasty.

They don't seem to bother anything in my tank!

Had them in my 30 gallon fowlr for a while and had coralline algae to burn. I've never had a problem with them. Can't beat a free starfish

They spread like wildfire!
Look for some natural predators if anything!
