@reedyspeedy12 I posted a link to my blog in the video description field where you can read all about the crabs. Pretty much the same information can be used for fiddler crabs as well.
@KingOfHeavenly Google is your friend. Brackishwater is water between freshwater and saltwater, with a concentration of about 2 tablespoons of marine salt per gallon of water.
thanks! i have about the same sized tank as yours, but i have freshwater in mine. does anyone know where to get brackish water? ha, i'm clueless! the pet store we went to, the worker, just said to put him in freshwater, but now i'm finding i should put him in brackish? whater that means!
Google for information on how to set up brackishwater and, more importantly, how to cycle an aquarium and keep the parameters good. Crabs are very sensitive to ammonia and nitrites. Brackishwater is water between freshwater and marine water. Not fresh, but not too salty. You need to add 2 leveled tablespoons of marine salt (NOT aquarium salt) to 1 gallon of water to make brackishwater good for crabs.
hey i really need this question answered. i just got my red claw crab yesterday, and he is missing a claw. yet he is very active, but he's not red he's sort of dark brown. are these signs of him being sick? i thought he lost his claw from a fight before i got him, but idk about the color.
Hey, you seem to know a lot about these crabs so I have a few questions. I just setup my tank today specifically for red claw crabs and just wondering how much land and water they need. I have a 20 gallon filled 3/4 with a big rock that has a surface the size of my hand. would this be good for 2 crabs? However the rock is huge and takes up a good 3rd of the tank
Given that space, I'd only go with one red claw. If you get two, you might have some fighting, especially over the rock that's sticking out of the water. Otherwise it sounds like you're covered. Just use a sand substrate and make sure the water is brackish and cycle the tank before you introduce the crab.
The rule of thumb is, never put 100% faith in the "pet store name", instead go by the scientific name. In this case red claw crabs are sesarma bidens. If red dwarf crabs are a diferent species, then you need to research that one.
You can give a crab anything, but you also have to realize that not everything is good for it. You can feed a human raw meat, that doesn't mean it's good for them. I don't believe in giving land/sea animals anything outside their natural enviroment, it's like feeding a dog, fish. Wolves as far as I know don't catch and eat fish. Why give it to them if their bodies aren't made that way. Again I'm not sure if wolves do or not.
Tigerbugwoman, you are absolutely correct and spitrhyma is clueless. For examp,e poultry isn't particularly healthy for these critters. I'm sure that in their natural habitat they eat a lot of chickens too ...
Im getting a male and female one tomorrow. i heard that they need saline water. How to i make saline water? need help!!! can someone please reply back Will be v.greatful thanks
By saline they mean brackishwater. You will need marine salt such as Instant Ocean which I highly recommend. Mix in 2 leveled tablespoons of salt per gallon of water.
BEFORE you introduce your crab, MAKE SURE your tank is cycled. If not, you will run into ammonia and nitrite issues, invertebrates are very sensitive to it and your crab will die. Also, the crab needs access to above the water so they can dry off. Otherwise it will slowly drown over time.
What did you feed your crab? I'm into feeding my aquarium animals a variety of food and am always interested in different foods. I just got a red clawed crab tonight. It's meal? Frozen Roe, I think it loves me. :D
I hope your crab is in brackish water, because they won't survive long in freshwater. Also, he needs a place above water where he can climb on an dry off. He will drown if left submerged.
Anywhoo, I fed my crab a piece of raw shrimp. They also love raw fish and all sorts of veggies: carrots, lettuce (hard to make sink) and especially peas. They love peas.
Yeah, I never get a pet without researching it first unless I know they really don't need a specialty situation. My crab is already in a tank with a slope up making an above water landing, it has plants and I added real sea salt last night, just enough to make it tolerable for my baby guppies (which my crab can eat if he wants) and my crab is happy. Tonight he got frozen brine shrimp. Tomorrow mostly plant like food.
Brackish water is water between full marine saltwater and freshwater. Red claw crabs and fiddler crabs need low-end brackish between 1.004 and around 1.008ppm. Look it up online and you'll find out more. Just note that you need MARINE salt, not aquarium salt to make brackishwater. Very few fish can acclimate, to name a couple: mollies and guppies. If you can't dedicate a species-only tank for your crab and care for it's well being, then I wouldn't get one.
I read on a few different sites that they can live in Freshwater :S Are there any Crabs that accually live in Freshwater; assuming those sites are incorrect
They can live in freshwater, but it will shorten their lifespan greatly and complicate their moulting. For long-term being and happiness, they need brackish. All red claws need salt in their water.
I used to use a hydrometer, but they are all very inaccurate for low-end brackishwater. So I bought a refractometer instead for about $30. VERY accurate
It's true, crabs need acces above water to dry off occasionally, otherwise they slowly drown over. Also, they absolutely need brackish water, keeping them in freshwater will significantly shorten their lifespan, weaken their immune system and complicate moulting.
The water needs to be brackish, which leaves you with very few choices of tropical fish you can have in there. A red claw or fiddler crab in full freshwater won't survive for long.
What conditions are ur tank? do u need salt in the water? is gravel better then sand? anything about them really! :)
Thanks

An ashy-looking crab can mean it is getting ready to molt. It should grow it's claw back. I hope you have good tank conditions.

Are you referring to the dwarf red tip hermit crab? Then no, they are a completely different species which are actually MARINE hermit crabs.

My 75 gallon palludarium has plenty of hiding places on dry land, yet they spend the majority of time in water. I'll get it on video sometime.

I am only having crabs. 2 i think. But im still not sure if the Red dwarf crabs i am getting are the same as these Red clawed crabs. Any ideas?

Try to find out what the scientific name is and we can go from there. Ask the store and send me a private message.

It's all real rock.

Mine will be in a fully tropical tank with an area out of the water. Is this ok?

The water needs to be brackish, which leaves you with very few choices of tropical fish you can have in there. A red claw or fiddler crab in full freshwater won't survive for long.
