New Catfish in Stock

There are more than 2000 species of catfish in the world and are most common in South America and Africa. They range in size from the tiny 2.5cm Pygmy Corydoras catfish to over 1 metre in length whoppers like the Redtail Catfish. They can make an interesting addition to most aquariums and are suitable for any beginner hobbyist.

Catfish can be kept within the community aquaria, and some catfish like the Corydoras catfish group happily spend a long time foraging in the daylight hours. But one must remember that most catfish are nocturnal, and they need rocks, caves, or drift wood, for cover in the day light hours. This is also important to remember as some find it difficult to obtain enough food, adding catfish tablets or other food after lights out is a good idea.

Different catfish species required different foods, some are Aufwuchs feeders which scrape algae and micro-organisms off rocks and wood, others eat vegetables, plants and wood matter, while some are more generalised and like anything from bloodworms, cyclops, brine shrimp, mussels, pellets, tablets and flake foods. Our shop staff will be happy to tell you the correct food requirements of your purchased fish.

Catfish can adapt to different aquarium water conditions and most will tolerate a wide range of pH, hardness and temperatures. But for the general rule its recommended to have a pH 6.5-7.4 with a temperature around 23-27ºC, but for the species from the African lakes (mostly Synodontis sp.) prefer a more alkaline hard water with a pH 7.5-8.1.

L-Number Catfish

In 1988 the term L-numbers was devised in Germany for group of catfish call Loricariid, it was meant to make these catfish easier to identify as the increased imports of these fish grew stronger. This system was very controversial, an alternative to the L-number system the “LDA numbers” was also devised by “DATZ” a German aquarium magazine standing for “Loricariidae Das Aquarium” which is still used today.

Otocinclus Catfish – Otto Cat

Otto cats are small underrated sucking catfish but are a great addition to peaceful planted tanks as they clean up undesirable algae growths on aquatic plants and decor. Although herbivorous on algae they may need additional supplement feeds of algae wafers and other veggie based foods. They also required clean well oxygenated water to thrive.

We have many Ottos (Otocinclus affinis) in store including some real rarities like the Zebra Otto (Otocinclus cocama), Black Otto (Ottocinclus negros) and the Orange Peru Otto (Hypoptopoma/Nannoptopoma sp.).

Feel free to take a look at our Catfish Stock list below.


Give us a call before you come in as many fish sell out quickly. If you would like us to order any unusual species for you, please give us a call and we’ll be happy to help.
