I don't think he's THAT old, but he's not young either. He looks huge in comparison to my super delta boys and the girl too. I put her in a cup floating in his tank just now, he's charging around, flaring and dancing to her. Looks super wicked. He made her horizontal stress bars disappear. I'd like to breed them but I don't have a spare tank.
Might try the Thai way, would a 9L bucket work? :-?
