It is thought that there are at least 100 species that have been discovered but not yet identified.
Can You Keep Different Corydoras Together?
Corydoras are a fairly non-aggressive type of fish and will cohabitate with corydoras from different species. However, they will not school together, so it’s important to have at least two of each kind so that a singular species does not stress out from lack of socialization. It is also important to have an aquarium tank large enough for each species to school separately.
What Are the Best Corydoras?
The best corydoras to purchase for your aquarium are ones that can withstand a wide range of water parameters, are easy to care for, and are not picky in their diets. Bronze and peppered corydoras are two of the most commonly kept species because of their low maintenance.
Pygmy corydoras are also very easy to care for, considering their small size, as long as you keep them in larger numbers.
Which Corydoras Are the Most Expensive?
The most expensive corydoras species are the rarest ones to find in the wild, including Evelyn’s corydoras, Panzerwels corydoras, and the Peru Black corydoras. They do not show up in the ornamental fish market too often and are sold fairly quickly because of their high demand.
Do Corydoras Clean the Tank?
Corydoras are bottom feeders that will eat algae growing on the substrate as well as uneaten food particles that sink to the bottom of the tank. They are very efficient tank cleaners as such, and some even go so far as to “dig” through the substrate to acquire fallen bits of leftover food.
How Many Corydoras Should Be Kept Together?
Corydoras are very social within their own species, and it’s best to have at least five individuals per species kept in a tank. They tend to school with their own species and can become stressed out if they are left without conspecifics. Ensuring enough space for all the corydoras you may house is also important to prevent overcrowding.

Recap
Corydoras come in many different varieties; in fact, there are over 170 named species and at least 100 more yet to be named. They all hail from South America, and most tend to prefer slightly acidic to neutral pH, warmer water temperatures, and soft to moderately hard water hardness. Most species enjoy having shelter spots provided by floating driftwood and leaf litter or rooted aquarium plants.
Since corydoras are social beings, it is best to keep at least five of each species you choose to purchase and be sure to provide additional nutrition on top of the algae and leftover food they’ll scavenge from the bottom of the tank. All in all, this family of freshwater catfish is fairly low maintenance and will help you keep your aquarium tank clean.
