These crayfish come from Mexican waters and are very easy to keep. Some breeders say it was a Dutchman who originated this variety in an effort to show off his country’s color- orange. These versatile crayfish are able to live in tanks as small as 10 gallons if given food regularly and good hiding places.  You should always have more places for them to hide than you have crayfish. They are more aggressive than other crayfish so you should only keep a male and a female or two if you’re working with a smaller tank. They will need plenty of places to hide and feel safe or they will try to climb out of your aquarium and are quite capable of doing so. 
The Dwarf Crayfish isn’t as hard on plants as some of the other crayfish aquarists keep and if given enough other food will even leave your live plants alone. You can give blanched veggies such as zucchini and spinach for treats. They will clean up your algae and excess fish food. In addition a high quality shrimp pellet should be added or algae wafers to enrich their diet. They will molt several times and eat their molted shell to salvage the nutrients. Many hobbyists will also tell you they love Java moss. As with many invertebrates it is often advised to give calcium supplements so their shells are strong. Males tend to have larger claws then the female and will pin her down during copulation to deposit sperm. She can carry the sperm for quite some time until she feels comfortable enough to release her eggs. Many hobbyists report a dip in temperature and then a climb back up will induce molting and berrying of females. If there aren’t plenty of hiding places when the larvae are hatched they will cannibalize each other (a danger when they are molting as well). These can be more aggressive than other crayfish that are popularly kept so it’s important to give them enough room, hiding places and food. Unlike many crayfish, they are not nocturnal so you will be able to enjoy their movement during the day. You’ll want to house with small, fast moving fish or shrimp as they may be able to catch larger, slower moving animals. Crayfish are fantastic escape artists and should be kept in a tank with a close fitting lid. They can climb and are able to live outside of water for quite some time. They are also quite hardy so please be responsible and do not release them into the wild.

    Arrived nicely, but died the next day :( i think he may have tried to fight the betta that was in his tank....and ultimately lost the fight. It broke my heart...not sure what to do.

    I was hesitant having never ordered anything "live" other than plants online, but I took a chance and am very glad I did! My two dwarf crayfish arrived safe and very healthy. I definitely would recommend them--don't hesitate--just do it! :)

    Posted by on 12th May 2014

    I never even knew that these lil beauties existed until I saw them here on elite inverts. They are active and constantly foraging and keeping the sand nice and clean.
    Thank you Elite Inverts for the prompt and courteous service.

  7. Best company to deal with! 5 Star Review

    Posted by on 14th Apr 2014

    I ordered 2 CPOs and was very hesitant when it came to shipping... I contacted them at multiple times and they always replied in a prompt manner, reassuring me that they will do everything in their power for the crayfishs to arrive safe. They did it! Not only they got here safe thanks to their great packaging, but they love their new house.
    I would for sure recommend those crayfishs and this company to anyone.

  9. Crayfish 5 Star Review

    Posted by on 23rd Feb 2014

    They arrived late because of a snowstorm but all were alive and are doing well. They are so cute to watch moving over my aquarium floor. I ordered 6 and gave 3 to my sister...we love them.

  10. Spunky and gorgeous! 5 Star Review

    Posted by on 11th Jan 2014

    These guys are full of personality and are just so much more fun to watch than my ghost shrimp! The orange coloring they exhibit is beautiful as well. They're pretty feisty too. When it's feeding time, they're definitely not afraid to stand up to other fish twice it's size and attempt a snip or two with their claws! Haha! Crawfish were packed very well and insulated. Highly recommended!
