Red clawed crabs are fun, fascinating little creatures that make great pets for your home or classroom. They are easy and economical to care for and their crabby antics like climbing, digging, molting and shell switching are as entertaining as they are educational.

These crabs love to climb, so be sure to have a secure lid on your habitat. They use fine hairs on their legs to scavenge for food in their bedding or substrate. One of the most fascinating features of these critters is molting, or shedding their outside skin in order to grow. Be sure to provide lots of hiding places like rocks or driftwood so they have plenty of places to hide and feel secure.

Bottom swimmers
You will see crabs swimming at the bottom of your aquarium or climbing on the décor.

This is a characteristic of crabs and means they need to shed their outer skin in order to grow.

Hiding places should be offered as crabs prefer a secure area as a retreat.

Juvenile crabs can be kept in a general community aquarium, but as adults they may harass their tank mates and should be kept by themselves or with other large, tough fish.

Staple diet
Crabs must be fed sinking pellet foods that they can find at the bottom of the tank.

Frequent feedings
For optimum health, feed your crab as much food as he will consume in 1-3 minutes, twice a day.

Red Clawed Crab is rated 4.2 out of 5 by 39.
Rated 5 out of 5 by from Great Pet To Have I bought one and it like to climb, hide, and fight with my fiddler crabs. Better to have in a large group than alone. Never escaped when in a group. Needs a filter to prevent smells. Over all, makes a great pet.

Rated 5 out of 5 by from Unique and Interesting pets! Red Claw Crabs are a fun alternative to fish for aquarium hobbyists. I have 3 of them in a half-full 10 gallon aquarium with driftwood and rocks sticking out of the water for them to perch on. A must with these crabs is an internal canister filter. I have a Whisper 2-10 internal power filter in my tank which keeps the water clean and creates a peaceful waterfall. Please do your crabs a favor and keep the water brackish (1TBSP salt per gallon). I also use a submersible heater to keep the water warm and a blue light to encourage my nocturnal crabs to explore the tank during the day. Use a lid which doesn't have any openings such as a screen lid or your crabs will escape! I feed mine API Bottom Feeder pellets. Overall these crabs are the most interesting aquarium pets I've ever had and I highly recommend them! I sit and watch mine for hours :)

Rated 5 out of 5 by from These crabs are great pets and can be housed with all sorts of fish in a large aquarium. They do not bother fish and will be fun and intriging to watch! I have 5 of these crabs in my 55 gallon tank with my pleco,sharks,snails,gouramis, and siver dollars. The crab does not bother any of them and he does not eat the plants either. My crabs do not seem to need sea salt, unlike fiddler crabs. The only problem is they love to hide all day. Other than that they are awsome!

Rated 5 out of 5 by from Sneaky little guy I got a crab to finish off my tank, and since we are Portland Trail Blazer fans we named him Allen Crabbe. I swore he went missing after the first night. I tore my tank apart looking for him because I was reading reviews on how some crabs escaped. I couldn't find him, I told my kids he went missing :( Later that night I went down stairs for some water and looked in the tank and guess who was front and center!! Allen Crabbe likes to barry himself (I watched with my own eyes) He has plenty of hiding places but for some reason he likes to barry.. no wonder why I couldn't find him, he matched my rocks haha! Great little crab, low maintenance, I believe we will get him a crab friend here soon.
