Overview

The Simulatus cory is a peaceful, long-snouted cory for the bottom of a community tank. It is a step up from the easiest fish.

Did you know

The Simulatus cory and the short-nosed masked cory form a famous mimicry pair. Why mimic pairs exist is still argued about.

Caring for the Simulatus cory

Keep six or more Simulatus cories over deep, fine sand in a tank of 20 gal (75 L) or larger. Add wood for cover, and keep the water clean and flowing.

Hold the temperature at 73 to 81°F (23 to 27°C) with a pH of 5.8 to 7.2. They eat the standard cory menu and dig deeper in the sand than Corydoras metae does.

Simulatus cories are peaceful, and you can keep them with their short-nosed twin, Corydoras metae, if you enjoy the visual pun. The mimic pair makes one of the hobby's neatest biology demonstrations in a single tank. Breeding is rarely reported, and it is hard.

Good to know

The Simulatus cory was named simulatus, the imitator, by Weitzman and Nijssen in 1970. It wears almost exactly the black bandit mask and body stripe of Corydoras metae, the masked cory. Yet it is a long-snouted species from a different lineage. It remains in Corydoras in the strict sense in the 2024 revision.

In the wild

The Simulatus cory lives in the upper Meta drainage of Colombia. It shares sandy stream beds with the masked cory it famously imitates.
