Two Different Clownfish

[T.W.]

I am still cycling my 20g High but when it is time I am wanting to get 2 Clowns for it. At first I was going to get 2 True Percula's. Recently though I have been thinking on 1 True Perc and 1 different kind of Clown. Since I will only have these 2 plus a goby I thought 2 different might add some variety instead of duplicates
Any combo I should stay away from? I don't want to have to separate any inhabitants if possible.

The only one that I would attempt would be an ocellaris, otherwise I for see issues.

I currently have a percula and a B&W ocellaris;

Cool. I just wanted a little variance because I will only have a total of 3 fish so might as well get 3 different lookers ya? B&W Ocellaris will work. Thanks
