The Emerald Fire Crayfish (Cherax holthuisi) is an emerald green and orange variation of its species and is native to Irian Jaya, Indonesia.  This crayfish is also commonly known as the Apricot Crayfish or Sunburst Fire Freshwater Lobster, though true lobsters do not exist in freshwater.  Deep emerald green and firy orange are distinctly shown on this crayfish.  The Emerald Fire Crayfish breeds easily in the aquarium, but the fry are extremely slow growing.  In fact, many of our specimens have bred in our tanks at our facility! 

This particular crayfish is relatively active and spends plenty of time exploring the floor of the aquarium in search of food. The Emerald Fire Crayfish is an omnivorous scavenger and will eat most any meaty or plant-based foods. This crayfish should not be kept with ornamental live plants as it will eat them at a surprising rate.

As it reaches adulthood, the Emerald Fire Crayfish will become relatively territorial, so it may behave aggressively towards other animals in the tank.  It is important that ample hiding places such as rockwork, driftwood, or PVC pipes be provided.  This is even more crucial when housing multiple crayfish in the same tank.  Due to the size and waste production of this crayfish, a minimum 30-gallon, well-filtered aquarium is necessary for one adult.  A larger aquarium of 55 gallon or larger aquarium can house multiple adults of similar size.  This is a reasonably hardy animal, but regular water changes are vital to its optimal health.  Other bottom-dwelling invertebrates and fish should not be kept with large crayfish.  It is possible to keep mid- and upper-level, fast-swimming fish with the Emerald Fire Crayfish, but crayfish are opportunistic feeders and will generally eat whatever they can catch. 

As with all of our crayfish, the coloration of the Emerald Fire Crayfish is EXTREMELY high quality - much higher quality than others on the market!  This crayfish may TEMPORARILY change color and hide more than usual after molting, which may occur during shipping. If your crayfish is not blue and you find a molt in the bag or in your aquarium, do not worry; this is normal and the bright color will return in 2 weeks or less.

    • 1 Emerald Fire Crayfish (Cherax holthuisi) - 3 to 4 inch Young Adult (No sex specified / Most popular option).
    • 1 B-Grade Emerald Fire Crayfish (Cherax holthuisi) - 3 to 4 inch Young Adult (All of our “B-Grade” crayfish are simply specimens that are missing legs or claws.  Loss of appendages is not permanent and happens commonly with crustaceans. They are completely healthy with excellent coloration and will completely regenerate lost appendages within 1 to 2 molts (about 2 to 3 months).
    • 1 Juvenile Emerald Fire Crayfish (Cherax holthuisi - 1+ inch (A younger and smaller variant of Emerald Fire Crayfish at a lower price than our young adult specimens. This is a particularly fast-growing, hardy species and will usually grow well into adult size and coloration within 1 to 3 months.  In the meantime, any customers who choose to go with a juvenile specimen can save some money and experience the excitement of watching their little crayfish grow!) 


What We Like About This Crayfish:
  • Consistently excellent emerald green and orange coloration
  • Less aggressive than many other crayfish
  • Easy to feed
  • Excellent scavenger 
  • Temperature: 68° - 85° F (20° - 29° C)
  • pH: 6.5 - 7.5
  • KH: 6 - 15 dKH
  • Minimum tank size: 30 gallons
  • Diet: High-quality sinking pellets, plants, and freeze-dried or frozen meaty foods will be readily accepted. Cuttlebone should be added to the aquarium to supplement calcium, which will aid in exoskeleton production.
  • Social behavior: Can be aggressive/territorial with other crayfish, but is much less so than Procambarus species such as the Electric Blue Crayfish.
  • Origin: Western Irian Jaya, Indonesia
  • Average adult size: 5 - 6 inches (12.7 - 15.2 cm)
  • Average purchase size: 3 - 4 inches (7.6 - 10 cm) or larger
  • Recommended Aquatic Arts tank mates: Fast-moving fish (such as Celestial Pearl Danios, Rasboras, Guppies, etc.). While dwarf shrimp can be kept successfully with these crayfish, caution should be exercised, as the crayfish have been known to catch and eat slow, sick, or particularly small shrimp.  Cichlids can be aggressive toward crayfish and should not be kept in the same tank. Bottom-dwelling tankmates should definitely be avoided.
