Long story short, my betta died a month ago from a long fight with parasites. I'm unsure what the exact kind was, but they were white, thin, a few millimeters long, and attached onto the floating log/plant in the tank.
Now, I'm very confused as to how he was infected with parasites in the first place, so I'm hoping someone here can help me. I bought him at Walmart, and two months later he started showing signs of a parasite infection (before that, he seemed and acted perfectly healthy). He never had any tankmates, and the only other live thing in the tank was an Anubias plant I bought when I adopted him.
Part of me wonders if he was already infected when I bought him (after all, Walmart is probably the worst place to buy fish), but I'm not sure how that would work.
