Different fish eat different amounts. Some will consume none while others will eat all available. Fish are opportunistic feeders and will therefore sometimes always act like they are starving and over engorge themselves if more than ample food is supplied. In a aquarium based setting a schedule should be followed where same amount of food is given roughly same time of day. If algae is persistent in an aquarium and a fish is purchased for this purpose, additional food shouldn't be added to the tank to account for this fish until either the fish is discovered to not be eating the algae or the algae is nearly gone. If the fish is sated on prepared food algae may be left alone. There are also other aquariums inhabitants in fresh and salt that can help with algae other than fish such as crabs and snails.

∙ 10y agoIt depends on the kind of algae. If it is the green film on your glass, your best bet is a Plecostomus catfish. They grow quite large, but small ones are available and most better aquarium stores will take it back in trade when it out grows your tank.
If this is a thick slimy film of algae that seem to grow on everything, nothing much will eat it and you should control it with better water quality. Changing 25% of the water in the tank once a week and good gravel cleaning as you change the water with a gravel syphon will bring it under control. Also be sure to limit the time the tank light is on to about 12 hours a day.
It you are talking about a green algae that grows in long fairly tough strings, just about the only thing that will eat it is an apple snail. It can also be controlled with the same water quality methods listed above.
There are a number of algae killing treatments on the market but most don't work very well. Even if they do manage to kill 99% of the algae then the decaying dead algae will only feed the remaining 1% and it will explode in growth (called an algae bloom) and you are worse off than when you started.
