What are these? (pics)

The white thing in the second pic is probably some kind of aptasia. Don't want them in your tank, either. There have been lots of threads on aptasia control. Just do a search for it for ways to get rid of it.

What size tank are you running?

I would keep the calurpa and get a foxface or some tangs in the future. I think it adds diversity to the tank, when kept under control.

Many of us grow calurpa in seperate tanks as a water filter, and to feed our fish.
