Before you do this, make sure your copperband is going to eat it. Also I would not feed this on purpose to a copperband because it is toxic and mostly water so very little nutritional value if any.

I would only raise aiptasia to breed berghia nudibranch, nothing else.

Sounds like you don't really know what your copperband is going to eat. Did he ate anything yet? Mine don't eat much anything else than live white worms (enriched with Selcon) and mussel flesh fresh.

It would be much better for your copperband to get a live white worms culture and raise those instead. Better chance of the copperband eating them and living long. I have been feeding my copperband with these for 2 years and he's fat and healthy.

For now you can buy some fresh mussel at the grocery store and open it in half and give your copperband one half of the shell with the flesh in it. Tie it to a heavy rock with a rubber band and he'll probably pick at it clean.
