Tank-raised specimens of this classic nano fish are difficult to find, but we have them! Compared to wild-caught specimens, tank-raised specimens are typically much more durable in the aquarium.
Whether or not you have an algae problem in your tank, Otocinclus Catfish (Otocinclus macrospilus) make a great addition to any aquarium community. Also known as Otto Cats, otos, or dwarf suckermouth catfish, these fish use their sucker-mouths to attack algae on the aquarium glass, plants, and decorations. In fact, they are widely considered one of the best algae-eating fish in the world, and groups of them form quite the cleanup crew with their voracious appetite for algae. They come from fast-flowing rivers in South America, so they do best in aquariums with strong currents (which can be achieved with good water filters or powerheads), good filtration, and plenty of aeration.
Otocinclus Catfish are recognizable by the rows of armor-like plating along their bodies. They often have a variety of neutral colors on their bodies (such as browns, grays, and black) that form attractive patterns. This fish should be kept in groups of 6 or more. These are small catfish, growing up to a maximum of 2 inches in length. They have very social personalities and are quite peaceful, making them completely safe to keep with other non-aggressive fish, shrimp, snails, and live plants.
If algae is not present in your aquarium, the Otocinclus' diets can be supplemented with fresh vegetables (such as cucumber or zucchini), algae wafers, or vegetable-based flake food.

Shipping Schedule for this service
Current Handling Time:
1-9 business days
Here at Aquatic Arts, we consider the welfare of the live animals we are shipping to be of the foremost importance. This process is much more involved than simply creating a shipping label and affixing it to a box. Depending on the order, it takes from 4 to 7 people to complete this process properly. We check the weather conditions here where they fly out of the Indianapolis UPS facility and the destination for each shipment. We start early each morning and go through a multi-step process to have the day's shipments prepared in time for the UPS pickup. The volume of orders in our system also affects the processing time. Therefore our stated handling time is 1-9 business days.
Shipping Rate
Pricing is by size of package needed to fill entire order and distance it must travel. It will be calculated at checkout.
