Adding new fish...

[stsmythe]

I have a yellow watchman goby in my 40 gallon tank and was thinking of adding a lemonpeel dwarf angel. Would it be a bad idea to add another yellow fish? Would the two fish try to attack each other?

Nope, you shouldn't have a problem with a dwarf angel and a gobie. It's not the color in most cases but the species you try to mix(like species, same species).

If you have coral in the tank, the angel may nip at it, other than that I say go for it.
