I gave it my best shot, but this thing just moves too much. It stayed put for a week and a half and I thought i was in the clear - re-epoxied all my corals in to place, and let things settle down. Started moving again yesterday. I'm over moving things out of the way for it, and I have too much money invested in SPS to risk it.
Don't really want clown fish if they're not in anemone, so I'd like to sell the pair that have moved in.
Here's the nem when it was in a more convenient spot:
It's about a foot across. Would do very well in a dedicated tank, or in a tank where the rockwork can be arranged so that it's marooned on an island it can't get off.
Edit: Forgot to list price! I'll take 60 bucks for all three. If you want one but not the other, let me know and I'll think about how I'd price them.
