Thanks, it's 2 years old now.
Prizm Skimmer, Magnum 250 cannister, T5 lighting w/ moons. 3 inch sandbed and about 90lb of LR. Nothing tricky or hi-tech, for sure. Oh, 1 powerhead, don't know the gph, but it moves a lot of water.
I'm probably over done on the LR but I really like the look of it.
BTW, I wouldn't scare my fish even as a last resort. That's self-serving and just plain mean, in my opinion. Just give them time. I believe they likely know the anemone is there. I don't think they are automatically "immune" to the sting. The clowns return again and again to an anemone to keep their tolerance up. It is my belief that it takes bravery for the first leap in to begin hosting.
