Hi! I have had my betta tank for almost a year now(!) but lately (within the past 2 months) I have gotten this white/clear stuff on the bottom of my tank that looks like slime. The stuff is kind of fuzzy and sits manly on the top(I have a small bridge and it sits on the top of it, not under it) and also in the plants. My tank is about 2.5 gallons, with one betta in it. I feed the betta pellets and make sure he eats all of it so there is none left over, at least not very many left over. Last week the stuff got so bad I threw away all of my rocks, plants, and decorations away and soaked the tank in bleach. After I bought new plants and rocks and the bridge, rinsed all of these off and placed in the tank with water that is conditioned with water conditioner. After 4 days I started noticing this stuff again. What is this? How do I get rid of it? Ohh and the tank does not have a filter, I had one but my betta got stressed from it so I took it out, then about 3 months later the goo started coming. Thanks!
