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.

They are completely healthy with excellent coloration and will completely regenerate lost appendages within 1 to 2 molts (about 2 to 3 months).

This is a particularly hardy species and will usually grow well into adult size and coloration within 6 months. In the meantime, any customers who choose to go with a juvenile specimen can experience the excitement of watching their little crayfish grow!)

- Diet: Crayfish are typically very easy to feed since they are mostly omnivorous scavengers. However, Cherax species can sometimes be a bit finicky. In addition to various plant matter, we have been feeding all of our Cherax crayfish frozen shrimp that is chopped into manageable pieces after thawing. We highly recommend that our customers at least initially offer this diet to their Cherax crayfish. In time, it is very likely that the crayfish will also accept high-quality dry foods, though a varied diet is required for optimal health, coloration, and activity.
- Warning! Avoid any food product, medication, or plant fertilizer that contains Copper of any form. Copper is toxic to invertebrates. Many commercial fish foods, medications, and plant fertilizers contain copper or more commonly copper sulfate. Always look at the ingredient list for any product going into the aquarium to ensure they are copper free.
- 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.
