Shop Otocinclus for sale at Tropical Treasures Wyo in Cheyenne, Wyoming. Otocinclus, often called Otos or Oto Catfish, are small freshwater catfish commonly kept in planted aquariums and peaceful community tanks.
Otocinclus are known for grazing on soft algae and biofilm from aquarium surfaces, plants, and décor. They can be a good choice for mature planted aquariums with stable water conditions and compatible tankmates. Live Otocinclus are available for in-store purchase or local pickup only. Live livestock shipping is not available at this time.
Why Choose Otocinclus?
Otocinclus are popular with aquarists who want a small, peaceful algae-grazing fish for established freshwater aquariums. Their small size and calm behavior make them a good fit for many planted tanks, nano aquariums, and peaceful community setups.
While Otocinclus can help graze on soft algae and biofilm, they do not replace regular aquarium maintenance. They should be offered supplemental foods when natural algae and biofilm are limited.

Great for Planted Aquariums
Otocinclus are often used in planted aquariums because they graze on soft algae and biofilm from leaves, glass, hardscape, and décor. They are small and peaceful, making them a good option for aquariums with calm tankmates and stable water parameters.
These fish are best added to mature aquariums rather than brand-new tanks. New aquariums may not have enough natural algae or biofilm, so supplemental feeding is important.
Ideal Tank Mates
- Tetras
- Rasboras
- Corydoras catfish
- Peaceful livebearers
- Freshwater snails
- Freshwater shrimp in well-planted setups
- Other peaceful nano and community fish
Avoid keeping Otocinclus with aggressive fish, large predators, or highly competitive tankmates that may stress or outcompete them for food.

Otocinclus FAQ
Are Otocinclus good for beginners?
Otocinclus can be peaceful and manageable, but they are best added to mature, stable aquariums rather than brand-new tanks. New aquariums often do not have enough natural biofilm or algae for them to graze on.
What do Otocinclus eat?
Otocinclus primarily graze on soft algae and biofilm. They should also be offered supplemental foods such as algae wafers, Repashy-style gel foods, or blanched vegetables when natural grazing is limited.
How many Otocinclus should I keep?
Otocinclus are social fish and usually do best in groups. A group of 6 or more is often recommended when tank size and filtration allow.
What are good tank mates for Otocinclus?
Good tank mates may include peaceful community fish such as tetras, rasboras, Corydoras catfish, peaceful livebearers, freshwater snails, and shrimp in well-planted setups.
Are Otocinclus shrimp safe?
Otocinclus are commonly kept with freshwater shrimp because they are peaceful algae grazers. Very small baby shrimp may still benefit from dense plants, moss, and hiding places.
Do Otocinclus replace aquarium cleaning?
No. Otocinclus can help graze on soft algae and biofilm, but they do not replace water changes, glass cleaning, filter maintenance, or proper feeding habits.
