hey y'all, I know this has probably been answered before but i just wanted to ask about my Ocellarius Clownfish. I have a pair that in my 20 gallon that i put in together and the larger of the two will not stop picking on the smaller one. I know that it's normal for the bigger one to be mean but anytime the little one tires to leave his corner she guns it for him. There's no chewed up fins and he looks healthy and he's eating. Anything i should be worried about or is it this something that happens a lot? Thanks
