Orange Dwarf Mexican Crayfish

Add a burst of colour and personality to your aquarium with the Orange Dwarf Mexican Crayfish, often known as the CPO Crayfish. This vibrant freshwater invertebrate is prized for its brilliant orange coloration, compact size, and fascinating behaviour, making it a standout addition to planted aquariums and nano setups.

Unlike larger crayfish species, the Orange Dwarf Mexican Crayfish remains small and is generally more compatible with community aquariums. Constantly exploring, foraging, and interacting with its surroundings, this crayfish brings a unique level of activity and character to your tank.

Its striking orange colour contrasts beautifully against green plants, dark substrates, and natural hardscape, making it a favourite among aquascapers looking to add visual interest and movement.

Aquascaping Notes

CPO Crayfish thrive in heavily planted aquariums with plenty of caves, driftwood, rocks, and hiding spots. A well-structured aquascape helps reduce territorial behaviour and provides safe areas during molting periods.

Their bright orange colour looks especially striking against green plants and darker substrates, creating a beautiful focal point within the aquarium.
