Hello! I am new here..I've registered to see if anyone can provide some insight on what may be wrong with my betta, Tide.
A few days ago, Tide became lethargic and didn't swim around as much. He used to come up to the top every time he saw you come in the room, because he was such a pig and always expected you to feed him. Now he barely gets off the bottom when I put food in, but he seems to be swimming alright when he does swim. He now has whitish patches on one side of his body, and I looked around online and I believe that it is some kind of fungus.
I've done a thorough cleaning of his tank tonight and put all the necessary water treatments in, so I'm hoping he will begin to heal. Is there anything else I should buy at the pet store to help him heal, or anything else I should do for him?
Also, here is a picture of what he looks like..Sorry that it's not the clearest thing in the world. My camera is from 2002!
