I have had 2 Ocellaris Clownfish for about 3 months. They were purchased as juveniles and were almost the same size. One was slightly larger. I dont' think they've paired yet. When will I be able to tell? The larger one is still somewhat aggressive towards the smaller one but never harms it (just chases it a bit) What should I look for? Will one always be a little aggressive towards the other? They are about 2 inches long and look much bigger than the juveniles I've seen around at my LFS. I'd appreciate any info someone could shed on the situation.
