angelfish can be aggressive (or moderately aggressive) and i haven't heard of or seen doll fish.
So they are both fresh water tropical fish? You don't just need the tank, you need lots of other equipments.
Please do your research first. There are lots of information online and in fish hobby forums. Don't just buy them....
When you need to start up a new tank, you need some starter fishes as well.

Well said well said!
I am not very good at expressing myself. But I don't want to see more fish being killed like that.
I miss my tanks.... and the sound of the filter...
