just have on mind, some of the Keyhole Limpets are considered as BAD, because they can and will digest your corals.
The other think about the limpets, is when they grow up a bit more (like 1/2 or 1 Inch) they can damage corals and destroy LR scape because they have really powerful foot to move.
Started removing limpets where possible after observing damage to peppa pig monti. Polyps intact, but pink color gone on a section.
I'm sure it will recover.
