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.

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

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.

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

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.

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.

Was very happy with this purchase, the CPO was a good size and very vibrant. Would fully recommend this specimen.

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! :)
