I got 2 clownfish i put the aggressive female in the breeder box to let the new gobies find out where they can go and stuff my tiger watchman goby is aggressive towards the female if she gets close. She was aggressive earlier but the watchman goby didn’t attack since it didn’t have a den to defend since I had to take the whole tank apart to separate the female from the goby so I’m assuming that’s why he wasn’t aggressive since I messed his den up but he made a new one not too long ago and I saw he nipped the male clownfish while I was leaving
