Stocking my Nuvo Fusion 30L, 3 fish vs 5 fish

[SonRK]

Hey guys

 

I really have no idea what to continue stocking my tank with now. Right now there are 2 Oscellaris Clownfish in there (I know, they should have been put in last).

 

Anyways, I'm trying to decide between 3 and 5 fish. I know if I go the 5 fish route, they would have to be smaller varieties, and if I choose 3 fish, I could go for something slightly larger.

 

 

Does anyone have an idea of what I should try to go for? I'm just trying to avoid having 4 fish, because that number is supposedly bad luck.

 

Thanks all!
