I have never really attempted an anemone before, but thought I'd give it a go. picked up a RBTA. Had it 2 weeks. Was eating great never moved from its original spot. It was open and extended nicely. For 2 days now it looks really depressed with a dark discoloration to tentical roots-tips still rose colored. It is responsive to stimulI as I see its tenticals react to copapods swimming in tank. Only thing different...I noticed one of my peppermint shrimp poking around at it the other night, but wasn't that bad. Lighting: MH, Amonia: 0, Nitrite: 0, excellent current Temp 78, 180 gallons What do you guys think?
