i keep a betta on my desk at school in a half-gallon bowl with some java moss and a marimo ball, along with a little castle-y type ornament. He's been outstandingly healthy since i got him, probably the most active betta i've ever owned. however, when i went to feed him this morning i noticed a few small, irregularly shaped pale spots on the top of his head. they're not raised like a fungus would be, and looking at them closely it looks like the larger patch is missing scales, and the smaller ones are either missing or faded.
any explanation for this? did he scrape his head on the castle maybe? his behavior hasn't changed at all, and he's eating just as well (viciously attacking his nice dead pellet food as always). my only concern is he's about to be shipped off on an eight hour journey home... he's handled this trip well in the past but if he's sick, i dunno.
