Rainbow crab is a pet?Imagine, this is really possible. Iridescent crabs, the photos of which are placed in this article, have long become inhabitants of the aquaterariums. Nothing unusual in that they are given more and more attention, no. Among similar ones, only the rainbow crab can boast such a vivid color and such a variety of palette. By the way, he has a lot of other names: indigo, patriot, tricolor, terrestrial. In Latin its name sounds like Cardisoma armatum or, respectively, Indogo crab, Patriot crab, Tricolor / Red / Blue crab, Land crab, Rainbow crab.
Among the crabs, he is one of the largest. The diameter of its shell can reach 20 cm. In this regard, the aquaterrarium for him must either choose at once large, or change as it grows up.
To begin with, the crab is iridescent, the contentwhich will require considerable trouble and effort, should have at least at least half a square meter per individual. With the content of a pair (or more) of such handsome people, a more voluminous (in length from a meter) aquaterarium is chosen.
The rainbow crab is rather fastidious and at times inordinately capricious. To create the living conditions will have to try. But beauty always requires sacrifice, does not it?
The bright blue armor (we call it the back) canto reach the density of colors to juicy purple tones. Brown feet do not have the usual whitish tear and are evenly colored. The pincers have several shades of red and brown at the same time and are the brightest at the junction, with their outer side paler. The abdomen may be bluish or pinkish, but more often white.
In nature, a rainbow crab chooses to settlecoastal sandy areas, digging out there are quite deep passages (burrows). However, it can also be found in remote places from the shore - such a removal is pushed by the lack of food in the main habitat.
Salty ocean waters are of interest only to crabstiming of reproduction. Thanks to this Cardisoma armatum it is quite possible to contain and in freshwater aquaterariums. True, a slight podsalivanie will be required when molting. Crab rainbow in the home does not multiply, because it refers to individuals of wild origin. At least until now, these beauties in the aquaterariums did not work.
Cardisoma armatum and peace forrelation to relatives. However, this directly depends on the mood of the crab. And it is very variable. It is interesting that the war between the individuals Cardisoma armatum does not begin immediately. First, an attempt is made to seize the house, then block the food with the whole body (which they get quite quickly). In case of refusal to leave the territory, the battle begins.
Quite a heavy load Cardisoma armatumtests at molting, which frequency is 1 time in 10 days in young individuals and 2 times a year in adults. At this time they go into shelter, so put more grottoes, shards, amphorae, etc.
Mark water in the aqua do not raise above 15 cm(over the surface should be elevated numerous sites and pebbles for rest). Do not forget that this is land crabs. For a ground choose pebbles, a crumb of a zeolite, tufa, a granite, a coral (fraction from 5 mm). Water, of course, should be clean, with frequent replacement and preferably with an artificial duct. Among the necessary equipment is an aerator and filter. It is very important to control the presence (or rather, the absence) of ammonia, nitrates, chlorine, which are destructive.
The adaptation period of a rainbow crab shouldsurvive in salted (sea salt!) water with a stiffness of 10 GH. The temperature should not exceed 25-27 degrees. Intensive greening of the aquaterarium is welcomed. Algae for the crab - and shelter, and feed. In addition, the diet of Cardisoma armatum should be squid, mussels, flour worms, bloodworms, liver (beef, chicken), gammarus. Quite useful for crabs is a mixture of sweet pepper (red), nettle (dry), calcium glycerophosphate (crushed tablets). Feeding is carried out only on the surface, on stony wide platforms. The ingress of food into the water will cause its decomposition, resulting in poisoning and death of crabs.
