Help Identifying what we got going on around his fin,
Chin, and maybe something below the fin?
Note:
1) The fin has been split since I got him.
2) Test show zero ammonia, zero Nitrite, 5-7 Nitrate
3) I do believe the ato got stuck on and salinity did drop from 1.025- 1.023
4) My clowns have been fighting but this joker has been the more aggressive.
5) He eats and been eager to eat actually chases down food more actively then other clownfish.
Been in tank around 30days.
Thanks for any help/thoughts
