This is a good problem to have. Most algae eaters enjoy munching on green algae. It forms a green powder like look on the glass or plants of an aquarium in high quantities. If your aquarium does not have any signs of algae you have some options:
Feed them Algae Wafers
This is found at a local fish store. They can be added to the water without fear of algae spreading. Some fish enjoy eating them and some seem to not like them.
Feed them Zucchini, not Cucumbers
If your fish don't eat algae wafers they might not be hungry due to feeding on something you don't see them eat. If you believe them to be picky you can entice them to eat and grow faster by blanching Zucchini and cut it into small sizes then add it to the tank. Rubber band it to something that sinks or poke it through with a BBQ skewer and stick it in the substrate. Don't leave it in the tank for more than 24 hours. Fish will not eat the skin.
Feeding Schedule
Algae eaters can survive on as little as 2 - 3 times a week feeding schedule. I feed my algae eaters once a week because there is plenty of micro algae that is unseen for them to much on. It depends on the species.
Blue Green Algae
Fish do not eat blue green algae. Almost nothing does. It looks like a blue green slime coating on rocks and plants and is a sign of bad water quality. It is actually a bacteria that uses encapsulated photosynthesizing algae to endure in harsh environments. Caused mainly by too much phosphates and not enough nitrates. Lighting may be a factor as well.
Are you talking about a golden algae eater? If so then they will eat any algae that is in your tank which is the green stuff that gets on the walls and decorations and if you don't have much or any of that you can feed them algae wafers which are green flat disks that you should be able to get at any fish store.
Most fish will not eat only algae, and will eat anything else you put in and leave the algae untouched, instead. If you want to add something to a tank in order to get rid of algae, I recommend a snail or some shrimp. Or you could take a clean rag and wipe it off the tank.
Generally it is a good idea to leave some algae. However, if you want to clean the tank very thoroughly and you are worried about the amount of algae left for your bottom-feeders, the best option is to buy algae discs. They are fairly inexpensive and you can find them almost anywhere that sells fish. They're located next to the fish food and usually a few discs will keep your bottom-feeders from going hungry until algae naturally grows back.
move tank away from any sunlight and/or cut down on duration of tank lighting (about 8-10 hours only), have 'siesta' period in between of 1-2 hours (algae needs long continuous period of lights). If really bad, switch off lights completely for a few days. move tank away from any sunlight and/or cut down on duration of tank lighting (about 8-10 hours only), have 'siesta' period in between of 1-2 hours (algae needs long continuous period of lights).

Guppies do eat algae. However, if you only feed it fish feed, then it will not eat the algae because it is so used to the fish feed...
It depends on what fish you have in the tank!
An algae eating species of any type isn't capable of eating all the algae in the tank. Your going to have to clean the tank yourself. The algae eater will from then on keep the algae levels in your tank down, but not totally.
Yes
It is probably getting into fights with some of the other fish in the tank.
None, algae indicates a problem that should be resloved.
you will need to get an algae eater, they are ugly but they do the trick, also a good quality pump
Nothing because no matter. What fish you have in there all algae fish is vegetarian so you don't have to worry about your algae fish eating others.
No. They only eat algae. They are no fish that are tank cleaners.
you can put an algae eater in with any tropical fish, I even have a goldfish in with my tropical fish now for almost 8 years. Pet store say no but i beg to differ. 8 yrs going strong, gold fish, algae eater, angel fish, silver dollars. Some fish are more dominate over others. I have learned no matter what they are if they are put in the tank, all as new fish as the same time, they all get along. After one dies, then as time goes on a new one has to earn its peck so to speak, so new ones get picked on. I have an algae eater and a cat fish. all is good.
No, as long as the light is not too bright. If you get castle or something to put into the tank, then it can stay in there without being directly in the light

Because I don't bother cleaning it. They bloat after they have been dead awhile. Are you using chlorine neutralizer and water purifier. Do you have algae eater.
