ok, so right now my betta is in a 1 gal tank. i am doing daily complete water changes along with cleaning the tank and rinsing the rocks off. i bought him a 5 gal tank with plants and accessories but until i get it on friday, this is my routine. anyways. i noticed that there is some white at the end of his fin. i'm not sure if i'm just being paranoid after reading about it, or if he actually has fin rot. so, i attached pics. if it is, how do i treat it? i know these aren't the best pics, it's hard to get good ones with just a camera on my phone :/ but if you need more, i will do my best.
