This is a beautiful fish that is very easy to find and extremely hardy. It is also known as the Blue Devil fish because it can be aggressive to other fish. They are very bold and can hold their own with larger fish. I've even had a couple of them try to bite my hand when I would put it in the tank.
They work best in the tank if you introduce them last. Otherwise they can become very territorial and aggressive to new tank additions.
