White bump bellow fin on clownfish

[marcosnano]

Hello reefers, I have a paired clowns but I noticed they will go into fight when the lights are down or when I put my hand in tank which is stessful for them and female will beat male.

I noticed some smaller injuries on male from time to time but today I noticed this big bump. Is it a injury or something else?

There is also a torch coral they are hosting.

Yes, this appears to be an injury from a bite or impact with object as larger clown can be aggressive. This should heal But you want to keep an eye out for both healing and on the other clown to see if there is an aggression issue going on here.
May not be a bad idea to acquire some seachem Kanaplex or Maracyn 2 to use for treatment should the area get worse or infected

While it does look like it could be a bite from the other clown that got infected, it is behind the pectoral fin of the fish. That isn't a very likely place for one clown to bite another - the fin would have had to be moved out of the way when the bite happened.
