The fish, up close
The Crayfish, scientifically known as Procambarus clarkii, is a freshwater crustacean that is popular in aquariums due to its unique appearance and interesting behaviour. They have a hard exoskeleton that ranges in colour from brown to green, and they are equipped with large, powerful claws. These creatures are skilled burrowers and enjoy creating intricate tunnels and hiding spots in the aquarium substrate. Crayfish are known for their scavenging nature and can be fascinating to watch as they explore their environment and interact with tank mates.
Care guide
Use these notes to shape a setup around the fish, then speak with our team about the tank you have in mind.
Plan your setupBehaviour
Crayfish are generally territorial and can exhibit aggressive behaviour towards tank mates, especially if they feel threatened or are competing for resources. They are nocturnal creatures, most active during the night, and may spend their days hiding in caves or under decorations.
Tank planning
Maintaining good water quality is crucial for the health of Crayfish. They require a well-filtered aquarium with plenty of hiding places and areas to explore. It's important to provide a secure lid for the tank as Crayfish are skilled escape artists. Additionally, regular water changes and monitoring of water parameters such as pH, ammonia, and nitrate levels are essential.
