Hey guys/gals, just wondering if anyone had any advice or tips to help reduce clownfish aggression. I bought a "pair" of clownfish around 2-3 weeks ago they are similar in size (one is slightly bigger than the other) and for the past week or so the slightly bigger clownfish has been frequently chasing around the other and occasionally nipping and grabbing at its fins. He is often trying to hide from her because of this. I know this can be a part of the process to determine which one is female and male but I'm concerned that the slightly smaller one may die if this continues for longer. Anybody have any tips?
