I've had him for about 3 weeks! I'm so happy! My third angel didn't get killed, he only ever gets nipped when my other two are trying to pair up (it will never work out for them, they are kinda lesbians) but he can just escape into the house in the tank! He doesn't show any signs of stress, and he is always eager to see me! Arrow( newest) Malibu(middle) Pine( oldest) Here's the whole tank! They seemed to be most interested in these: Why rocks though?!? Yay!
