ugh. My poor fish. I swear I try SO hard with him. Good news is, the white flaky spot is fading but now there's a white spot under his CHIN! It's not fuzzy, stringy, etc. It's like someone took a white marker and put a tiny little >> I << on his chin. It's a straight slit and it's very small. I'll try to get a photo... Anyways, his behavior hasn't changed. Only added med is Binox and that was for 4-5 hours about two days ago, I then transported him to his normal tank because I felt bad for him in a measuring cup (I was in the hunt for an actual tank for treatments because Squeaky is occupying my normal one). Anyways, the ammonia level is normal, temperature is at a constant 76, and I think it could POSSIBLY be a cut from maybe a plant. Is that possible? What would cause a white "gash" like spot?
It could be cottonwool, a fungus that causes fluffy, white, yup you guessed it, cotton-like growths commonly at the sight of a wound. So if he nicked himself, it's possible he's gotten cottonwool.
If the growths aren't fluffy, then he could have Columnaris or Mouth Rot/Fungus. "Small, off-white or grey lesions or marks concentrated on the head, fins, gills, and mouth cavity." - [i]A-Z of Tropical Fish Diseases and Health Problems/I] Columnaris is actually a bacteria despite the common name Mouth Fungus. So any treatment you'd use for a bacteria would work.
Yeah I feel so bad for him. I swear it's always something. I bought him from Walmart about 6 months ago and he stays the sickest out of my 4 bettas. I'm eventually going to put my newest, Squeaky, in with the other two in the 10 gallon tank and give Wartooth his own 5 gallon tank. Just testing the waters with Squeaks to make sure he's not sick either.
