I have a pair of clownfish in my 30g and a pair of clownfish in my 80g. The female in the 30g is pretty mean and picks on the male and the pair of clownfish in my 80g are calm and peaceful. My question is can I put the pair of clownfish from my 30g to the 80g or will they all fight? I also have a pair of chromis in my 80g, can I add another chromis or will they fight to? Thanks!
