It's a very small, almost clear string as described in the picture above. It appeared out of no where. I don't feed live food, I have an unheated 2.5 gallon tank. I'm currently treating him for fin rot, and feed him regularly. Chemical levels are unknown.

FIRST OFF, I'M SORRY THIS IS SO LONG!!! IT'S ABOUT A 2.5 MINUTE READ...MAYBE 3 MINUTES IF YOU READ THE "ADDITIONAL INFORMATION" SECTION. I'm taking a stimulant prescribed to me by a doctor and I makes me talk (and type) non-stop.:lol: <---Me talking. It's a little frustrating but I digress...
