I've got one, and noticed it being very aggressive in my LFS
, chasing around some pyjama cardinals. I was also told they can jump (my tank is open-top), and can bother shrimp. But, I got it anyway!
3 weeks later, it's doing great. It was hesitant to feed at first, but now comes right up to the surface along with my Ocellaris clown, to feed almost from my hand. It's much more timid than the clown - the dottyback rushes and hides if I stick my hand in the tank, whereas my clown rushes TO my hand and bites/nips it! Also, it's slower than the clown to get to the food, and still slightly hesitant. This is sorted by just putting more than the clown itself can eat at once, so while he's eating the dottyback can get some
He's not bothered my blood red shrimp ONCE, although the shrimp is usually in hiding. He's also not bothered my clown at all, or anything else, he's been very peaceful! He does stare closely at the shrimp, but he's never gone for him.
A fantastic fish, awesome bright colour.
