A mated pair, the female is almost 3" long and very aggressive - she bites me the whole time I'm trying to clean the front glass unless I shoosh her away - then she'll stay away for a few seconds. It does get tiresome. LOL. One day I may need gloves.
I always wanted to get a big anemone for them but didn't want the hassle of trying to get one to stay put so I never got one. When the pulsing zenia grew huge they decided it was a lot like an anemone and now the male hardly comes out...just to eat. They LOVE it. LOL.
They do their dancing thing around, looks like they're spawning but I've never seen eggs.
