I have three bettas, all of them are in 2 gallon + tanks. I have plastic plants in all of them. I have noticed the last few weeks that the plants are getting fuzzy. i do a complete water change every week and treat with salt, water conditioner and a drop of anti-fungal stuff. The fish are all fine and don't have any fuzzy stuff on them. It only seems to be affecting the plants. I've had it happen in two of the tanks before, and i rinsed the plants under extremely hot water, and they seem to be fine now, but the third tank is now showing fuzzy stuff on the plants.
Any ideas what it is? Or how I can prevent it from happening again?
