Frequently Asked Questions

Algae eaters thrive in tanks of 20 gallons or more. This is because they need plenty of room to swim and hunt down algae in their environment. That said, they can still survive in smaller tanks, provided they are well-maintained and there is enough algae for them to consume.

What type of algae eater is best for a 20-gallon tank?

When stocking a 20-gallon tank with algae eaters, the best options are Bristlenose Plecos, Otocinclus Catfish, Siamese Algae Eaters, and Nerite Snails. These fish and invertebrates are peaceful and relatively easy to care for. They will also help keep the tank clean by consuming the algae that grows in it. For best results, it is recommended to keep a combination of these species in order to maximize their algae-eating potential.

What kind of decorations and equipment do I need to keep my algae eater healthy?

Substrate: Algae eaters require a substrate that provides hiding places so they can forage for food. Sand or gravel that meets aquarium safety standards is ideal.

Filter: A quality filter is a must for healthy water and the removal of waste. Canister or hang-on-back filters are recommended.

Lighting: Algae eaters prefer dim lighting, so LED lighting or fluorescent lighting is ideal.

Plants: Live plants will provide cover and food for algae eaters, and will also help keep the water clean and oxygenated.

Decorations: Rocks, driftwood, and other decorations will provide hiding places and surfaces for algae eaters to graze on.

How Often Should I Feed My Algae Eater?

  • Adults: Feed adult algae eaters two to three times per week.
  • Juveniles: Juveniles should be fed three to four times per week.
  • Live Foods: Live foods such as brine shrimp, bloodworms, and tubifex should be offered as an occasional treat.

Note: Be sure to monitor your algae eater to make sure it is getting enough to eat, but not too much. Overfeeding can cause an algae build-up in the tank and can lead to other problems.
