I'm a new member to this site, but I have used it quite often to learn more about my (relatively) new Betta fish. I have a male betta, named Leo, which I got early December.
PROBLEM: Yesterday, I did a full water change (tank: 2.5gal). He seemed fine, as he swimming around and he ate his food. However, today I noticed a white spot on the left side of his head, a little below his eye. I'm not sure what it is and from the research I've done, I think it may be a parasite? The tanks has silk plants and no other sea animals living in there. He is still swimming around just fine, but I did notice him brushing against some plants/objects.
Please help! I am extremely worried for him. This is my first betta (first pet fish!) and I have come to adore him.
