Best Algae Eating Freshwater Fish?

Your tank is overstocked as it is, you don't want to add another fish or any other critter for that matter. More poop = more food for the algae + worsening water quality. For now your best bet is getting an algae scraper.

A single goldfish needs 80 litres of water and double filtration, which sounds like an overkill for a tiny fish, but they are supposed to grow to 8 inches at least.

Since goldfish are large, cool water fish it's tricky to find them tankmates. They are best kept with similar type of goldfish. This means that you can't really have algae eater fish with them. Some people have kept Bristle Nose Plecos and Rubber Lip Plecos with their goldfish successfully, I wouldn't recommend them since they too prefer tropical temperatures and would add considerably to the bioload. (Any other plecos have a record of sucking the slime coat of the goldfish.)

Algae eating fish as a rule just eat algae. Take a appear at the other way up catfish or plecos. 29 gallon shall be first-class for the other way up catfish, but a number of plecos will need larger tanks. I have a pleco that's over 1 foot lengthy

While certainly not an expert ..I can tell you from experience like the other replies a Cory would work very well. I have always used cory as well as other "cleaning" fish. For their size they can't be beat. They are very entertaining for your child...especially if you have a couple. They randomly shoot to the top of the tank and work always cleaning gravel and other items. Most stores sell them when they are very small..and this would work for you. They come in several varieties including albino....which would be easily seen...and are very hardy. This will prevent you from having to explain why little "fishy" is no longer in the tank..LOL. I kept a tank for my niece and believe me it's easier to pick hardy fish than to explain why one is on holiday. Many other options would open up with a heater added. Just an added note..a larger tank is easier to care for and maintain...just a thought. A good rule of thumb is an inch of fish length per gallon...so keep this in mind when adding fish. Good luck...and enjoy!

plecos are one of the best but they can get pretty big. If you have a smaller tank you could get a cory catfish they are small but do a good job and are very friendly. My favorite is the saimese flying fish they get to be about 3 inches long sometimes more i have a saimese flying fish and they are awesome. they do a good job keeping it clean. But be careful they jump out of the water if they are frightened so i suggest you have a lid for the tank.

Any other fish is much too large for your aquarium.

An oto or cory cat could be in it, if your aquarium was more than double the size.

You can ONLY have snails or/ and shrimp.

End of story.

Stop telling him/her to get plecos and other fish, they are WAY too large.

Your aquarium is JUST TOO SMALL.

You cannot have pleco in a coldwater tank - snails are the answer.

A single Apple snail is what you need - apple snail actually live longer in coldwater than they do in tropical you should feed them ocassionally with sunken cucumber - one or two of the same sex you definately do not want snails to breed.

You can get tiny baby plecos or Chinese algae eaters. The Chinese algae eater will take a while to grow and they are very through.

Ive got a pleco and hes so cool and does the job quite well but snails are good as well they are so cool as well

without a heater, i think a pleco would be best, but if you decide to get a heater, a otto, or chinese algae eater would be best

go with the pleco

I guess those ones I used to call sucker fish. They stick to the glas. I would get any old kind.
