one of my tanks has 5 xray tetras and 6 zebra danios and a little catfish. i feed the catfish a few sinking pellets each day and if he doesn't eat them they get all broken down and white fuzzy stuff grows. i vaccuumed it out but it has never happened in any of my other tanks. any idea what this is? thanks!

To me it sounds like some kind of bacteria bloom. I'm not 100% sure though...

Food can get moldy sitting in the water.

Its mold/fungus.... you should remove uneaten food like sinking wafers and pellets after an hour or so to avoid this.
