Was wondering, How many different pairs of clowns can i put in my nano? I know from my size that i can add 5 to 6 fish of about 6cm. Am i allowed to get like a pair of tomato clowns, a pair of occilaris clowns etc in 1 tank or will they dual to the death? if not, fight night tomorrow at 11. I got money on Coral, shes a greedy little bugger... Just kidding. but still....
