Was just going to ask you about the Mertens....Glad you still have it.
Those are an awesome anemone, but need space and dedicated and knowledgeable aquarists to keep them.
Based on what I've seen, you've got that covered.
I just wish that healthy S.gigantea anemones were more common here in St Louis.
The only healthy one I've seen was at a local hobbyist's house, and he stated he just ordered a blue carpet from the LFS and that is what they got him....acclimation was dump the bag in the tank.
