7 Cory catfish Species for Your Aquarium Tank

All Cory owners love them. Almost all Cory species should live in schools. There are many stories about Corys pleading for help when they feel lonely. Corys should only be kept with peaceful, small- to medium-sized fish.

What is a Cory?

Cory is a type of catfish. They are peaceful, bottom-dwelling scavengers that are small and quiet.

Like all catfish, Corys are bottom feeders and scavengers. However, they do enjoy a meal of brine shrimp. They can help clean your tank by eating uncooked food or other debris.

Corys can make a mess by digging through the substrate and introducing algae and other muck to the water. They can be part of the tank’s “clean-up crew,” but they will need help from shrimp, snails, and other scavengers.
