+1 limpet

good critter correct? any downside?

They are wonderful algae eaters but have an extremely hard radula so they can irritate corals. I had several at one point that had an insatiable appetite for GSP, although no one believes me. I have pictures to prove it.

Gotta keep that GSP under control somehow.

Reefcleaners.org sells them and provides information on them.
