Lol they can, like anything else with fangs or teeth. Some are more defensive than others. Isabelle's species is well known for their fairly nasty attitudes and speed. Shes kind of like a gold fish. They're for watching, not for touching.
Hehe thanks! Shes the only one I have left. I used to have just over 50 of them but I sold them when I purchased my haflinger (lol they paid for some tack and 3 months board!). I couldn't sell her because she had a cyst on her abdomine but she molted out of it! =D I'll see if I cant find some pics of my other ones..
