Mixing firefish?

[woody283]

Ive got a 30 cube and am looking at some peacful fish. Ive allways like the firefish. Would there be any aggresion twords each other if i were to put a purple and red in the same tank? trying to keep it as peacful as possible.
currently there is a tailspot blennie and i will be adding a pink streaked wrasse soon.

people say they are aggressive, but I have not personally seen it. there was a thread about a week ago about this same question

I thought i saw somthing like that but my searches weren't coming up with the thread. Ive done it before with a 65g but i only had them for about 2 months before my tank crashed after a move. I dont know about in such a small area thou.
