I've heard they are, they dont catxh my interest for most of the colors though. My friend had (has?) One, but she was so aggressive, especially with food in the picture. I think my friend ended up rehoming her to someone more experienced because she was having to wear gloves and was worried about her smacking the glass when she came close to the tank
They don't excite me because they don't get very gurthy, rather remain really slim, so you can't really see much of their color
