This is a free-floating type of algae. Algae-eating fish can't do anything for this. You can control it by keeping the tank lights off and removing any excess nutrients from the tank by continuing to do water changes (use a gravel vacuum to siphon any uneaten food and fish wastes from the gravel). You don't say how often or much water is removed when you do a water change, but I'd suggest at least 25% of the tank volume weekly. If you're already doing this, you might want to increase the frequency to daily if the problem is bad. The fewer individuals there are in your tank, the less reproduction.
Have you had your water source tested for nitrates or phosphates? You could be adding these to your tank without knowing it, and these act like fertilizer for your algae. If this is a problem, you can get phosphate pads (you cut a sheet to fit in your filter) to remove phosphates. You could also switch to reverse osmosis water, which will remove both from the water. you can get this in larger supermarkets at self serve dispensers (I get mine for saltwater tanks at a local Super WalMart for $.25 per gallon).

How long are you leaving the light on and how much are you feeding? both of these things, if overdone, can causes algae. It sounds like you have "green water", which is an algae bloom in the water. You'll need to reduce or cut-off the lights for several days (3-4 is good) and do at least one GOOD water change during that time. This would include changing out about 50% of the water in there, plus vacuuming the gravel. This should clear it up. I would stay away from putting chemicals in the water.

Sounds like an algea problem.Even though there may not be direct sunlight, the room the tank is in may have to much indirect light or if you are leaving your tank lights on for extended periods of time, this could promote algea growth.
Do you have any live plants in the tank? If not get some as they use up the nutrients the algea lives on BEFORE the algea can.

You could get some algae eaters, that may help
