Hi, I posted about this a few months ago. There is a white mass on my betta. I was told previously to try aquarium salt to treat it, but the spot has grown since then. My betta is less active now and mainly just lays around all the time. I put him in a cup just to deep clean his tank today and was able to get better pictures of it while he was in there. Iām not sure what it is and if itās treatable or not. This is my first betta so Iām pretty new to all of this. Any help would be appreciated.
