There are pretty good if you want to keep your algae low, and the are fun to watch, but they do grow quite long so I would not get one if you have a tank that is taller than it is long. Algae eaters are very good for long tanks. If you put them in a small tank they won't have very much space to swim in.

algae eater review
I got one of these algae eaters a little while ago and I think their quite adorable fish with easy care, but there are some things you need to know before getting one:
1) Do not get one for a tank less than 10 gallons. I had mine in a 3 gallon tank and it moved all of the décor around even if I buried in gravel. I now have a 10 gallon and the little girl is very happy.
2) You need lots of plants and decorations for them to hide in. If you don't, it won't matter what size tank they're in THEY WILL DIG.
3) if YOU Have a snail as well, you may see the algae eater less because there will be less food in the tank.
Other than those 3 things, the algae eaters are very peaceful, cute and energetic. They make an amazing addition to any freshwater tank!

Beware, not good for comm. or semi-agressive tank.
I bought this fish cause it was only a dollar and boy do you get what you pay for. I didn't know much about them except that they are supposed to love algae but in reality, they love the slime coats of other fishes. I thought the fish were playing together and then I noticed the dull patches showing up on the sides of my fishes. He goes after any fish: my Jack Dempseys, Tiger Oscar, and my Parrot Fishes, all more expensive and better looking then he is. Was, he's swimming with the fishes in the sky now.
