Caring for Otocinclus Algae Eaters, commonly known as Otos, requires attention to their specific needs. Here are some guidelines for their care:

  • Tank Size: Provide a tank of at least 10 gallons. Otos are social fish, so keeping them in a group of 3 to 6 individuals is recommended.

  • Tank Setup: A planted tank with hiding spots and soft substrates is ideal. They appreciate low to moderate lighting. Floating plants can help diffuse light and create shaded areas.

  • Water Parameters: Maintain clean water with stable parameters. Ideal conditions include a pH of 6.5 to 7.5, temperature around 72°F to 78°F (22°C to 26°C), and water hardness of 2 to 15 dGH.

  • Diet: Otos are primarily herbivores. Offer them a variety of foods, including algae wafers, blanched vegetables like zucchini or cucumber, and occasional live or frozen foods like brine shrimp.

  • Algae: While Otos consume algae, they can't rely solely on it. Provide supplementary food to ensure they receive proper nutrition.

  • Tank Mates: Choose peaceful tank mates that won't compete for food or harass them. Avoid large or aggressive fish.

To maintain the highest quality, all fish undergo a one-week quarantine upon arriving at our warehouse before being made available for sale. This practice helps ensure the health and well-being of the fish we offer to our customers.

Live aquatic life is exclusively shipped on Mondays, Tuesdays, or Wednesdays. If an order is placed between Wednesday and Sunday, it will be held until the following Monday, unless overnight shipping is selected. This schedule might change due to holidays or other unforeseen circumstances.


As with all live animal sales, there is a risk that they may arrive dead (DOA). If this is the case then a picture of the dead fish WITHIN THEIR ORIGINAL UN-OPEN BAG must be sent to us. 

If the fish die anytime after they are released into their tank, that responsibility falls on the owner and no refund can be provided. 

Furthermore, to qualify for the Live Arrival Guarantee, you must be present to receive the fish during the first delivery attempt. If you will not be home for delivery we suggest you arrange for the delivery service to hold your package at their facility for pickup, allowing the package to sit on your porch in extreme hot or cold weather is obviously not the best option for your new aquatic life.
