How to take care of Fiddler crabs?

Question

So i went to walmart the other day and I bought fiddler crabs. I didn't know they needed salt and Oxygen. In walmart they didn't have a place to get to land. So i didn't know and i bought them. I heard that they needed to have a high Hp. If that's true how high does the Hp have to be. Will they die if you a pinch of Table Salt/Iodized Salt? I only added a little bit. What kind of salt do they need and how much salt you need to put. I have to crabs in a 1 gallon fish tank. I only have it burly have way full. Where could you buy it too? My crabs are kinda big. I bought them 3 days ago. I have 2 crabs. Please help. If their is other information i need to know please add it in your answer. Thanks for everything.

Answer 1

The fiddler crabs sold in pet stores generally come from brackish water lagoons. Because they live in lower salinity water, pet stores may call them fresh-water crabs, but they cannot survive indefinitely in fresh water. Fiddler crabs should not be kept in fresh water more than a few days. Individual crabs should be perky and active and have all their claws and legs. Fiddler crabs can also be found in coastal areas in mud and sand inlet beaches and marshy areas at low tide.



A ten gallon aquarium will house four medium size (1-2 inch) fiddler crabs with sufficient space to prevent aggression. Prepare a sloping sand area for the crabs to bury themselves. Brackish water fish can be added in larger aquariums. Fish such as platies, mollies, guppies and swordtails as well as ghost shrimp will adapt to moderate salinity.



Carbonate Hardness (KH) and pH: Fiddler crabs do well with a pH or acidity of 8.0-8.3. Carbonate Hardness (KH) should optimally be between 150-350 ppm but crabs and some fish will tolerate higher levels.



Substrate: Fiddler crabs do not do well if they are deprived access to dry beach sand or dry to moist rock surfaces.



Temperature: Fiddler crabs do well in a range of temperatures between 75-85 F (24-29 C). If fish are kept in the tank the temperature may need to be regulated more precisely.





FOR MORE INFORMATION JUST GO TO YOUR LOCAL PET STORE AND THEY WILL TELL YOU. THEY WILL ALSO HAVE THE SUPPLIES. PETSMART OR PETCO OR WHATVEVER IT IS WHERE YOU LIVE.

Answer 3

I fell into the same trap too at Pet Supermarket. They had their crabs completely submerged in fresh water and from my research after purchasing the crabs, that is BAD! I initially bought 2 male crabs and before I knew it, one had escaped in the house! He had crawled up the airline hose and escaped and we just happened to see him skittering across the floor! I found out that fiddler crabs really need a tank with part water and part sand. DO NOT put table salt in your crab's water, you should get some aquarium salt and add 1 tsp. per gallon of water. They can stand it a little saltier, but from most of what I read, 1 tsp. per gallon will do it- they don't need saltwater, just briny water. I moved my guys to a 10 gallon tank with a screen top lid to keep them in. I bought some play sand from the hardware store and on one side, I barely put any in and then made a slope going up to about 6" on the other side. I added rocks on the low side for them to crawl and hide under as well as a bubble stone. I also added a small filter just to help keep the water clean. I put a stump decoration in as well- they love to play "King of the Mountain". I did go buy them a couple of "girlfriends" and it has been a lot of fun to watch the guys showing off for the ladies. So all in all, we have 4 fiddlers in a 10 gallon tank, which is the max you should have in a tank that size. We alternate food for them- we feed them shrimp pellets one night and then algae tabs the other. They are scavengers and will eat most anything, but a good diet for them is both protein and plant based. Hope this information helps and enjoy your crabs!

If the heating pad is for tropical tanks then it'll work good. If not you may need to get an aquarium heater. The biggest mistake people make with fiddlers is they don't give them an area to climb out of the water. They need to breath air too!
