Question about getting rid of Aptasia?

Caution with the Copperband, it is hard (read-almost impossible) to get
this fish to feed on manufactured or cultivated non-living food.
Please don't use this fish unless you have the matured and lightly fish
loaded reef tank with refugium to support it. Most people don't.
Course, correct me if I'm wrong and there is a good way to feed this
butterfly.

I'm pretty much a newb as far as this goes with only a few years
experience under my belt but I've had a copperband in my tank for a
couple of months now - purchased to rid the tank of Aiptasia which it
did over the course of a day - and it's still happy and healthy. It's
just starting to nibble at things like grated prawns but has always
eaten its fill of frozen mysis and brine shrimp.

100g display, 40g in the 'fuge and sump, DSB.
