Copperbands in a Reef

[LoJack]

I would say moderately reef safe. One of the most reef safe in terms of butterfly's.

I had no issues with mine ever touching SPS. But they liked to nip at the flesh of LPS, especially acans and blastos. Zoa's are usually on the menu but I never kept zoas in my tank, so that didn't matter. I have an SPS dominated tank with a little bit of LPS here and there and the Copperband never nipped enough to kill or damage anything ...

The biggest issue is getting them eating. You need an extremely mature tank for success unless you see them eating frozen at the LFS. Very very very hard to get eating. If you have an LFS where you can buy live blackworms, you will have a much better chance at success.
