Hi, I lost my first betta to either old age (3 years old) or a bacterial infection he couldn't fight. I bleached out everything (except gravel, which I tossed) and rinsed, rinsed, rinsed. Bought a new betta who came with a lump, diagnosed as lymphocystis, which he died from within 8 months but developed secondary infections of fin rot and possibly internal parasites. Anyway, I'm wondering if bleaching the tank is enough, snice lymphocystis is a virus and is contagious. Shoudl I toss the filter, heater, tank divider and tank? Thanks.
