The Aspidoras raimundi, sometimes called the "False Corydoras" is a terrific community fish. As a schooling fish it should be kept in groups, and will exhibit maximum social behavior in larger groups. Its native range is restricted to the Parnaíba River basin in Brazil.
The Aspidoras genus is one of the groups of fish called "armored catfish", getting its name from the Greek word for "shielded skin". Similar to Corydoras, and often indistinguishable to the naked eye, Aspidoras differ in that they possess supraoccipital fontanels. Supraoccipital fontanels are soft pieces of tissue between plates of the skull, which allow the skull to reach larger maximum sizes than their similarly-sized Corydoras counterparts.
Lineage 2 "Aspidoras"
Corydoras type fishes come from 9 distinct lineages. For the most part, the species in the Brochis, Aspidoras, and Scleromystax lineages have already been assigned to distinct genera. The remaining lineages are also likely to be split into their own genera once taxonomists get around to reviewing the groupings.
Most Corydoras are perfect citizens in a peaceful community aquarium. There are hundreds of species with a wide range of colors, patterns, and fin shapes. Affectionately referred to as Corys, these small catfish are always entertaining as they clown around together searching for food. Most are 100% non-aggressive, relying on their heavy body armor to protect them. Corys live by the phrase "make love, not war," spawning in large communal aggregations without combat or displays of dominance. Because of their peaceful nature, there is never any worry about stress due to bullying or hierarchy disputes.
Something interesting about these catfish is how they supplement their oxygen intake by breathing atmospheric air. They do this by darting up to the surface, taking a gulp of air, and darting back down to the substrate. This is perfectly normal behavior which adds to the charm of their clownish behavior.
Corydoras can be found on a wide range of substrates in the wild ranging from mud to sand to rock. However, all the species we have kept have greatly appreciated a substrate of fine sand which they constantly sift through for food, often burying their faces up to their eyeballs as they push into the sand. Fine sand is not strictly necessary and they will do just fine on a wide variety of substrates, or even on the glass bottom of an aquarium, but, if you can provide sand, you will see a lot of really enjoyable behavior as they root around for food.
This fish is highly gregarious and only truly thrives when kept in groups...the bigger the better.
Corydoras need protein rich foods in order to thrive. Unfortunately, they are often sold as "cleaner" fish with the expectation that they will get enough nutrition by sucking algae and other gunk from the substrate. While they do need some plant matter in their diet, they are not effective algae eaters. In fact, for optimal health, it is recommended that they be target fed a variety of sinking pellets and wafers, as well as the occasional offering of frozen and live foods. They can eat quite a lot, but are somewhat slow feeders. We have found that regularly feeding long-lasting foods such as large pellets, wafers, and Repashy and letting the Corys graze on these foods for a few hours at a time helps keep them fat and sassy.
