LOL, I was just kidding. The female is about 20x bigger than her babies, so no chance of mixing them up! Yes, she still has her mate. They laid their first nest in the re-done tank tonight.
Poor boy. She's been beating him up, too. Maybe the nest will settle her down, except they picked a very bad spot for eggs -- too far from their sleeping spot and the sinularia host they picked won't provide any protection like their old frogspawn did -- so I think it's likely the eggs will only last for a night or two before something eats them, and then she'll beat up the male for losing the nest. :rolleye1: Well, he DID pick that spot.
Very few mandarins will eat out of a hand; I'd think you'd have to train them in QT not to fear the hand at all, unless they were captive bred (and there are some CB mandarins out there). Maybe the goal is for them to come sit on your hand to eat. I don't think they are engineered to pick things out of fingers, if that's what you are trying for. Is he eating prepared foods?
