product highlights

Aptly named, Algae Eaters are often placed in large aquariums to help keep algae from overgrowing. These bottom-swimming fish feed on green algae and vegetable matter, moving along the surfaces of your aquarium scraping green algae with their suckermouths. They also eat all kinds of commercial flake and pellet foods, but must get sufficient algae and vegetable matter, such as fresh zucchini, romaine lettuce, spinach or spirulina pellets. You will see your algae eater swimming at the bottom of your aquarium. They will also hang from plants and the aquarium walls, using their suckermouths for attachment. To create a beautiful aquarium environment, be sure to add some middle and top swimmers as well. Ask a PetSmart associate to help you choose.

Things to Remember

Frequent Feedings
For optimum health, feed your algae eaters as much food as they will consume in 1-3 minutes, twice a day. You can alternate between regular staple diet feedings and 2-4 meals per week of a vegetable treat or specialty food. Remove uneaten fresh vegetables after four hours.

Adding Fish
Whether you're just starting your aquarium or introducing new fish into your tank, don't forget to add only 1-3 at a time.

Unique Gill Opening
Algae eaters have a special opening on their gills so they can breathe without loosening their grip on a rock or other surface.

Minimum aquarium size should be 10 gallons or larger. A good rule of thumb is one gallon of water for every one inch of full-grown fish.

Decorate their aquarium with hiding places such as roots, driftwood and rockwork. Also include plants to provide grazing surfaces.

Fish Compability
Algae eaters should not be kept by beginners or in a community aquarium with delicate fish. As adults, they can be aggressive to other tankmates and should be housed with large, tough fish or as a single species in the aquarium.

Note: Note: Pet availability is seasonal. State and local regulations may vary. Pricing may vary by store location. PetSmart stores cannot match the price above for this pet. Ask a store associate for details.

Algae Eater
2.19 New Out Of Stock
Algae Eater is rated 4.2 out of 5 by 62.
Rated 5 out of 5 by from Two Golden Algae Eaters Mine arent full goldens, they were a cross between the regular stripped one and the goldens. So they have Golden heads and upper chest, but their bottoms are stripped. They are neat. These guys have moments where they like to hide, for the most part, mine are out in the open eating and playing with my cichlids. Yes, I said cichlids. These two are housed in a 29 gallon tank with an infant firemouth cichlid that is currently about 2 inches, as well as an orange blossom peacock cichlid that is fastly approaching 4 inches. The peacock LOVES to play with my smaller golden, she will mock him by trying to stick her mouth on the tank next to him, and as he moves up, she moves up. My largest golden is about 2.5 inches, while the smaller one is just under 2 inches. The larger one prefers to be left alone and quickly swims away if another fish gets too close. The smaller one LOVES the company of the other fish...and often tries to follow the larger golden around, in which case the larger one tries to swim away from him. As far as their cleaning abilities go, no algae eater will keep you from having to clean your tank regularly. They would be good at keeping the green algae off the glass, but they do nothing for cleaning of gravel and decor, although they try their hardest. Hardy fish that are active and always out and about in my tank.

Rated 2 out of 5 by from Tank terror Sure, these guys will eat algae when young but as it gets larger, its appetite for algae slows and it can start latching onto other fish. Years ago, when I was inexperienced with fish, I bought one thinking it would help control algae. It did for a short time but then started killing my other fish. Lost 2 angels and a clown loach. This fish will seem to be non-aggressive when small but when it grows, there's a good chance you'll have a problem. I've heard nothing but horror stories about these guys. Be careful if you choose to add this fish to your tank. The name is deceiving. A much better option would be to get a few otos, amano shrimp or an American Flag killifish

Rated 5 out of 5 by from Algea eater I have one it is so cute and really good he eats up my snails leftovers. his name is Auto

Rated 5 out of 5 by from Excellent work! I have 1 of these in my 50 gallon aquarium. It cleans off most algae and is super peaceful with my other fish I currently have 2 German Blue ram cichlids and they do not seem to bother it most of the time. I recommend this algae eater for highly skilled fish owners because it gets so big and is different then other fish.

Rated 5 out of 5 by from Algae Eater These little algae eaters are really cute when young and are a great alternative to the plecos. They eat more algae when young and tend to eat more fish food than algae when older.

how log does it take them to be 11 inches

Asked by: jacksonvefg
It would not grow 11 inches or let alone 1 inch before it's dead or disappear. It last at most 6-8 weeks in the tank. I have 18 of them in a period of 3 years. Some eats algae, some just stick on the glass and some is being eaten by the algae itself. Base on experience, 2 out of 10 will eat algae and won't be enough to clean the tank entirely. That is your job NOT algae eater job.
