An interesting solution to polyp picking fish!

[ScubaSteve]

I found this article today while I was making my usual rounds today and thought it was quite interesting.

While we don't typically keep obligate corallivores, we do keep the odd angel or other fish that like to munch on our prized SPS. This might be an interesting way to train a polyp picking fish off your corals and onto other foods.

Cheers!
