In all actuality, you're not going to get any fish to solve your algae problem. When you set up your aquarium, you started a new ecosystem in which you're in complete control of. You're Mother Nature now. Algae is caused by too much light, and nuitrients in the water. Mother nature has her own ways of solving it's problems. By allowing water to constently change and flow. Either from underground water sources, rain, snow, current. There's a hundred different ways. Now it's all up to you to solve this problem. Is your tank setup where it's getting a lot of direct sunlight? If so, there's your #1 problem. How strong is the wattage of your lights, and how long are they on? Are you vaccuming your gravel, and doing proper water changes? Yes, there are certain fish that will feed on algae, but you can't expect them to solve this problem. You took this so called new ecosystem you started, and condensed it down to a very small area. And when not taken care of properly all your asking for is disaster. Remember when this happens in nature, and water quits flowing and it get over grown with weeds and algae. All the oxygen is starved out and everything begins to die off. This isn't a slam against you or anyone else. But like I said in the beginning. Now, it all up to you to keep everything going and running like good ole Mother Nature does it. Good Luck.
