Aiptasia eating butterfly fish

[Reef Pilot]

I have Pearlscale butterfly fish, and they totally cleaned up my aiptasia problem. They also taught my Copperband to eat aiptasia. If well fed, the Pearlscales won't eat my coral, but if hungry (not fed well), they will pick at my mushrooms and palys/zoas. They leave most of my other corals (soft and LPS) alone. I don't have any SPS, so not sure what they would do to them.

I am more suspecting an aiptasia only diet to be bad. But that was just my impression after reading a lot of these stories. Maybe the fish also ate all the aiptasia and died because it was not eating anything else, not sure.
