I second that joeybsmooth

. I have a lot of younger cousins around(ages 3-7) and they used to bother Sora, until one day she just bit one of them when I wasn't around to moniter her(I swear she had a triumphant gleam in her eye lol). I felt bad, but hey, the job got done. They no longer bother her and have learned to watch her from a safe distance, from infront the glass of the tank

. And surprisingly, Sora is not aggressive or snappy at all, before and after the act of her biting them

(I don't condone abuse of children via animals or in any shape/form, but hey. Theres only one way to learn sometimes, and that's the hard way unfortunately.)
