those are some nice crabs if they are land crabs i would take the water out till its about one inch high and there is dry land for them
No no... its from the family Grapsidae...the most commonly imported member of this family is Sesarma bidens also known as "The Red Mangrove Crab"
It is one of 25 species from South-east Asia that all resemble each other. These Sesarma do not really live in fresh water, even though they do eventually march to fresh water from brackish areas and so cope well with fresh water aquarium conditions. If you want to keep them healthy, just add some salt to the water.
If you want more information look for the Aqualog book...

It should be brackish, and this is best achieved by adding abit of sea salt or Iodine free table salt.
It is also important that their home is well covered so that the necessary atmospheric humidity, more than 80%, can be maintained. The air must be constantly warm. Its temperature, (28 to 30 deg C) should be a little warmer than the water, (24 to 25 deg C) as otherwise the crabs may catch cold.
If you want a natural surrounding for a group of these crabs you should setup an aqua-terrarium. Not too shallow because you have to fill it up to a certain level with sand, so that the crabs can build their holes. A small water reservoir ( just a quarter of the availiable space) so that the crabs can breath without difficulty when they are in the water. You will then see how the "used" water is expelled via the mouth. At the same time, the crabs should be able to life their respiratory openings ( which are to be found at the insertions of the waliking-legs) above the water level.

I don't think so. Appearance especially the dorsally-compressed ovoid composition of the cephalothorax and presence of both white and red morphotypes - is entirely consistent with that of a Neotropical Gecarcinid - see http://www.wirbellose.de/arten.cgi?action=show&artNo=115.
