when it want to go to left, it left legs will grasp much more deeper than the right legs
when it want to float to the water level, it will increase its leg movement
when it want to go to inclined direction, it main body will move to match the direction

Freshwater crab breeding
For the best breeding, separate all the crab or group by type
Crab eating habit
Generally, crab need to eat 10-20% of its body weight and like to eat strong smell and entire food
It like to eat on land.
Even the environment is good
It is unsure
crab need to eat food every day.
Sometime is because crab stored the food in the body or prepare to change the
cover.
Crab change cover
Normally, crab change cover around 5 minutes otherwise may lead to death. But the total process need three days to complete.
Firstly is to change cover by leaving from the old
cover. (Successful process with freshwater is critical)
Then the new cover is very soft just like soft sweets and it need
around 1 day become harder,
In day two, it will search for food to recover the energy and growth.
In day three, you will find it become bigger obviously.
Summary
Freshwater crab is hard to pet and breed. Because they need to change the cover from time to time. And every time they change it, if the condition change, they may die. Also, they must breed in certain condition, e.g. most of it may follow the tidal. So it may not easy to let it breed.
