what would eat grape Macro

[BMW Rider]

I got two corals from them last week too and both had a bunch of it growing on them too. I just picked off and scrubbed off as much of it as I could. I do have a yellow tang that should take care of any new growth. Turbo snails might keep it in check if you can remove the bulk of it first. Thats just a guess though.

One of my corals was an acro also, and it had some of the red bugs on it too. I treated it with interceptor which I still had from my last experience. I'd suggest you have a good look at your acro for them too since they are probably from the same tank at Ocean Aquarium. It also had a bunch of pom pom xenia growing on the base. I scrubbed it off too since I really didn't want it in my display. If I could have fragged it off, I would have kept it for my 50 gallon, but there was no way to do it.
