The female is a good 4 in., and the male is about 2 1/2 in.
They're eating brine shrimp out of my hand. Well, at least the female is.....she won't let the male get close enough to take any.
(He gets left with the scraps, I guesss!)
I think they're beating up my RBTA, though. Individually, I think they would be fine with it. But, when they both get in there, it's just a bit too much for the anemone. I've tried to re-position it in the tank so as to block off their access to it. Hasn't really worked too well yet, but I'm still trying.
