Possible case of brookynella

[J8kpin]

Hey guys,

My clown has been great till 2 days ago,
When he stoppe eating vigerously and keeps avoiding me when he sees me. His color is still there, but he is still eating but just a piece or 2 of flakes. What should i do? Is this brookynella? I am new to clowns, so i never have encountered brookynella before. He has been in my tank for abt 2 months and was not quarantined. He is a percula clown. Any help works.

Thx
