The Red Claw Crabs are very attractive with black or very dark maroon bodies and red claws.

| These Red Claw Crabs and the Gold Fiddler Crabs are truly aquatic and do not need to get out of the water. They can live indefinitely on the bottom
of your aquarium completely under water. |

in your web sites you says that red claw crabs do not not to come out from water as well as the fiddler crabs. well
this is not a correct information, Both Species need to come out of water from time to time. red claw crabs are fresh water where as fiddler crab are brakish water crabs.
thanks

Hello Farhan. Thank you for your comments. You may be right, but both of the types of Crabs, that we sell, do well for us in
freshwater.
We keep these Crabs in big aquariums with very shallow water, but I have kept Crabs in smaller aquariums, where they could not get out of the water, and they did fine for a
long time.
Other aquarists have told me that their Crabs have done well in aquariums similar to mine. But it would be best to give the Crabs a choice by placing a big rock or pile of
rocks that extend up out of the water and allow the Crabs to climb up and out of the water.
The rocks must be arranged carefully in such a way that will not allow the Crabs to get out of the aquarium. It would be interesting to carefully observe the Crabs to see if
they enjoy getting out of the water and to see how much time they spend out of the water.
It would also be interesting to arrange a light above one side of the rock to see if the Crabs enjoy basking in the light, or if they stay on the side of the rock away from the
light.
I would like to try this with both a small incandescent light bulb and perhaps a special wide spectrum light bulb, like the bulbs recommended for reptiles.
Thanks again for your comments. |

These Crabs will escape from your aquarium unless you make sure there is nothing near the vertical pieces of glass for at least 4" above the bottom of
your aquarium.
So move the rocks, ornaments, and all the other objects away from the glass. Shorten the length of the siphon tube to the filter, so the strainer is 4" above
the gravel. Make sure there are no pieces of airline tubing the Crabs can use to crawl out.
Here is an interesting email comment sent to us by David, after he visited this web page.

I came across many posts on various boards asking for help in controlling snails, and cleaner tanks etc. I think I
found a very good solution. Crabs and crayfish: Crabs eat the snails! I had about 12 of the little snails that usually come on live plants and I noticed the Crabs eating them so
they are keeping them under control in my tank. Like you already have on your Crab info they help keep the tank clean.
Also though they help aerate the substrate a little. I use sand and they are very good for it; they sift through the very top layer about 1/4 inch all day long looking for food
which helps keep the sand loose etc. The crayfish does the same but it goes in a bit deeper maybe 1/2 - 3/4 inch down sometimes. So It seems there are a few extra reasons to have
them in a tank |
|
|
|
1. |
Scavenge bottom of tank - helps keep it clean
|
|
|
|
|
2. |
Keeps snails under control
|
|
|
|
|
3. |
Helps aerate, loosen substrate which helps the biological process better - especially sand
|
|
|
|
|
4. |
They appear to "groom" live plants of unwanted junk also without harming the actual
plants |
|
|
|
|
5. |
They are fun to watch.

| Reply. Thank you, David, for your comments about your Crabs. If you see something interesting and useful while watching your fish or
other animals, send us your comments and we may include them in this web site. Like we did with David's interesting comments about his Crabs.
Incidentally, we do not recommend using sand in aquariums or fish bowls, because the water does not circulate well through the sand, and it soon becomes polluted. You can
substitute a thin layer of aquarium gravel that is at most 1/4" thick. Click
here for more about aquarium gravel.

This picture shows a Male Gold Fiddler Crab. You can tell he is a male by his large right claw at the top of the picture. Females do
not have oversized claws. To some people with lots of imagination these large claws look like fiddles, so these Crabs are called Fiddler Crabs. Males often climb on top of something like
a rock and wave their large claw. |

| Gold Fiddler Crabs are very attractive and interesting to watch. The male Gold Fiddler Crabs have one large claw and one smaller
claw. The females have two smaller claws.
The males often climb on top of a rock, hold their big claw up, and wave it back and forth. Why? We don't know, but we'd like to know. Click

for the answer. |

Appropriate Home
An aquarium with an
external power filter with a BIO-Wheel and a
maximum of 1/4 inch of
gravel. These Crabs can live in an aquarium with or without an aquarium heater at a temperature of
about 65 to 82 degrees F. Many of these Crabs prefer water from 75 to 82 degrees F. Be sure the Crabs can't escape, or they will escape.

Recommended Diet
Crabs will eat almost anything such as particles of flake food that sink to the bottom of the aquarium and
other bits of food. For this reason they are excellent scavengers and help improve the water quality by reducing the amount of uneaten food in the aquarium. They also stir the top 1/4" of
gravel and help keep it clean.
But they are not a substitute for cleaning your aquarium and changing some of the water. Click
here for more
about cleaning aquariums.
Crabs will eagerly eat live and frozen food such as blood worms and brine shrimp. We give all of our Crabs an occasional treat of live food such as live Black Worms. Click
