Had stone crabs split oysters and clams wide open and eat them. Your doing the right thing to catch them.

Rocketter... thats ok, I got hung up as I was leaving and didn't even make it to the meeting at all. I found that you can tease the aiptasia off the rock, so long as you can get to the foot of it, using a sharp pointed set of forceps. They don't seem to like being poked with that and will peel off pretty easy with the forceps after a little poking. If there are hundreds and they are not in holes, it will take a while doing it, thats for sure.

Nudibranch rental - thought about that. Actually these things will be really great for a nano-reef and other smaller tanks. No impact to pH like the juice does and maybe the person would get to see them now and then to retrieve them. In a large system, probably never see them again. And if someone tried peppermint shrimp but didn't get them all out, these nudibranches could be lunch on a dark night.
