i just did a full water change
there are only three white spots, but they are on the top of him in order
the surface of the water had lots of clearish brown clups of fuzzy stuff, and there was alost of stuff along the top part of the walls of the tank
its a small tank (only half a gallon) so i can't buy any filter or anything
i just cleaned the water three days ago, so it can't be lack of cleaning
anyone have any suggestions
