I love them! I've had mine about a week. They remind me of puppies! So shy at first then crazy curious. If I sit at the tank and just look in he will spot me and come investigate looks me right in the eye too. And if I pull out my camera even if he's all the way across the tank he'll just stuff his face right in front of me, to the point I can't get a good side shot cause he is too interested in what I'm doing. So cute. His girlfriend isn't quite as curious, but I'm sure she will be in time. Named her Sparkles. I want a bigger tank now!
