AQUATIC CREATURES IN CAPTIVITY
Since there has yet to be any proper documentation of how these crabs thrive in captivity, no one knows what really happens to them while in tanks. But for most animals, stress is expected when in captivity, starting with transport from their natural habitat to the store, then from the store to the buyer. There’s also the issue of being taken from a huge lake to a small tank. Even if you decorate it beautifully, the size and surroundings won’t compare to the real deal.
While information is available regarding the proper care of these crabs, not everyone can do things right all the time. In inexperienced hands, these crabs may suffer and perish, just like any other animal. In the wild, they may have a better chance of multiplying as much as nature needs to sustain the ecosystem and keep it thriving.
