Similis Corydora, Corydoras Similis, is a small and peaceful shoaling catfish. Also known as the Smudge Spot Cory, they are endemic to the Rio Madeira basin in Brazil. Wild caught fish are rarely found in the aquarium hobby these days though, with the vast majority being captive bred specimens.
The Similis Cory is a lovely species of cory. The body is a pale tan or olive, and dark almost blue spots cover the body with a dark spot at the base of the tail.
Similis Corys are generally easy fish to care for, providing basic needs are met. They do best on a fine substrate, either sand or micro gravel. Corydoras will root around in substrate looking for food, so sharp substrates can damage the barbels at the front of their mouths. Other décor is largely down to personal taste. Areas of cover will provide security, resulting in more outgoing and active fish.
Corydoras thrive best in clean water with stable parameters, with a pH of between 6.5-7 being ideal.
Similis corys are not an easy species to sex when young. As adults females are considerably larger, and tend to be rounder and broader-bodied. Males are generally smaller and slimmer. A ratio of one female to every two males is ideal if attempting to breed them. Corydora are a shoaling catfish, and thrive best in groups of 5 or more.
Similis Corydora feeding requirements
Similis Corydora are omnivorous in diet and will eagerly accept dried, frozen, and live foods. A good quality protein-based tablet or granule is ideal as a staple diet, supplemented with frozen food enriched with garlic and vitamins. This will ensure good health and vibrant colours. Live food, especially tubifex and bloodworm always goes down well too!
Here at the Abyss Aquatic Warehouse we believe in only providing the best for our customers. All of our fish are fed a varied diet of dried and frozen foods. Also, we ensure they are in perfect condition before they are shipped out.

First time ordering from Abyss and wish id come to you instead of another well known company! My group of 6 were all bagged individually, a mix of male and female as requested, lovely size and all very healthy. What more could you ask. Excellent service, great quality fish, brilliant aclimating instructions (im very familiar doing a slow drip aclimate but I’m impressed the details were there), all healthy, active and settled in straight away. Suffice to say i won’t be returning to the other well known company thats closer to me (*dead fish on arrival and errors in selecting in my last 4 orders! Refunded but thats not the point). Id highly recommend you guys and will be back.
