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.

    Just checked my paypal and that account is active and ready to go for Monday.

    I didn’t but ok. It quoted me at $8.12 for shipping. Is there another method besides PayPal? I do not have an active account but I can make one if necessary.

    Thanks Chris, is this is the email of your paypal account as well? I'll need to create an invoice to bill you for shipping. I won't know the cost until I create the label on Monday. When I create the label for the package I will send you the paypal invoice. You can go back to your account on at the website and see that you selected in-store pickup. Its the first option above priority mail, so you must have selected in-store by mistake.

    Thanks for understanding!

    I did not select in store pickup. I live in Charlotte, NC. I also selected a shipping option that said 2 business days and expected them to be consecutive because of the nature of the product.

    Thank you for reaching out. I understand and have no problem with it.

  2. simba 5 Star Review

    Posted by on 9th Jan 2020

    I love my new dwarf cray fish he has such a personality and so much spunk! When he came in the mail he was really cold and I thought he was dead but I gave him a chance and still in his bag floated in my tank for almost two hours to slowly warm him and sure enough he was still alive. He’s the smallest thing in my tank but he’s the boss!!

  3. Perfect Addition to my community tank! 5 Star Review

    Posted by on 30th Nov 2019

    My new dwarf crayfish is a lovely new addition to my community tank! He is always out in the open, scavenging leftovers on the aquarium bed. He is small but one of the more lively characters in my aquarium. For anyone that wants something slightly different than just normal shrimp, this guy will be a great addition to most small aquariums, just a little small for anything more than 10 gallons or so, but perfect for nano-aquariums!

    No problems

  5. Energetic and colorful 5 Star Review

    Posted by on 26th May 2017

    I ordered 3 of these CPO crayfish. They arrived in perfect condition and started exploring my tank as soon as they were released into the water. They are very colorful and healthy and quite active. The largest of the 3 tends to be somewhat of a bully, but the other two are holding their own.

  6. cutest cray ever! 5 Star Review

    Posted by on 9th Dec 2016

    I love my little cray fish! He is soooo adorable! ! He came in a little bag and completely unharmed ! Way smaller than I expected but that's fine...I love him and I plan to order from this website in the future

    Larry the Lobster (my new CPO Dwarf Crayfish) settled in nicely and is doing well with a Beta and several Ghost Shrimp

  8. "Mr. Krabs" 5 Star Review

    Posted by on 10th Nov 2016

    The crayfish arrived healthy and very energetic. The box was packed with insulation so the fish won't get shaken around much. The company cares a lot about the fish and their customers. I was slightly worried about ordering an animal online but overall it was a very good experience. Very happy and would recommend.

  9. i love it 5 Star Review

    Posted by on 17th Mar 2016

    When I got it I was so happy. He came 2 days early. When he arrived, he was packaged properly, active, and very healthy. He molted within 2 weeks of arrival. I am going to warn everybody though, they arrive very small

  10. Came in great condition...in the middle of 12 degree Chicago winter. 5 Star Review

    Posted by on 18th Feb 2016

    I ordered two CPO dwarf crayfish in early February using typical USPS cheapo shipping. I wasn't sure if they would make it in the 12 degree Chicago winter, but they did fine. I let the bags acclimate to room temperature on a table before acclimating them via Elite Inverts' excellent acclimation instructions page.
    After one week, I have had no issue with these little bitty crayfish or their tank-mates.
    They share a 75 gallon, heavily planted community aquarium with a variety of fish. Julii cory cats, otocinclus, upside down cats, glass catfish, a golden dojo loach, a LARGE gourami, a sailfin molly, a school of neon tetras, a male fancy guppy, and endler's live-bearers. There have been no altercations between any of these fish and the CPO dwarf crayfish.
    They like to crawl along the glass of the tank and on the plants. The children really love to find them among the plants. They have made an attractive addition to my peaceful community aquarium. They are active and are seen often. I would advise this purchase to anyone looking for a cool, but not dangerous/aggressive crayfish for a community aquarium.
