ENGLISH:
Aquascaping Lab by Tommaso Perini and Serena Sacchi present a video on Cherax crayfish Shrimp or Blue Lobster, and all the species of f Parastacidae family , derive from New Guinea, Indonesia and Australia. Cherax is a freshwater shrimp, has an exoskeleton that in nature is not very colored but in breeding varies, from green water, to blue and bright blue, and depending on the species, orange, brown and violet. It has a body with 10 legs, 2 of which are equipped with powerful claws that it uses to prey and bring food to the mouth positioned frontally. The Cherax species we know are many but the most famous and used in home aquariums are:
Cherax Quadricarinatus, has a bright blue color and comes from Australia.
Cherax (Astaconephrops) Pulcher has an iridescent color from blue to purple to pink and comes from Indonesia.
Cherax Peknyi has a dark brown or black color with yellow or white reflections and derives from the New Junoea.

Cherax sp. Blue Moon has an intense blue color and derives from New Guinea.
Cherax Destructor has a light blue color and comes from Australia.
Cherax Tenuimanus has a dark blue color, sometimes black or dark brown and comes from the rivers of Australia.
The Cherax, like many species of freshwater crayfish, live in streams with not very strong currents, with a sandy and rocky bottom that they use to hide and hide. In nature it can grow up to 20 cm so we recommend 50 liters for one, otherwise it could develop badly, or even collide with other similar or fish that invade areas of its level. This shrimp is extremely predatory and territorial, with their claws with teeth, in a short time they are able to grab a fish, cut it and bring it to the mouth. Therefore it is advisable to avoid cohabitation with small fish such as neon, caracidae and other small crustaceans. it is absolutely not suitable for aquascaping preparations treated in detail as it will spend most of the time digging, moving stones and cut the stems of the plants to make the burrows and hiding places.The difference between male and female can be noticed by two details. The male, starting from the tail near the paws, has two small growths, while the female at the third leg has two small holes, moreover the male specimens have claws more developed and colored than the female instead, has more long-limbed claws. The latter also has a more developed abdomen, to contain eggs . The Cherax shrimp is an omnivorous and predator.

Vivono in torrenti con corrente non molto forte, con un fondo sabbioso e roccioso che usa come nascondiglo e tana. In natura può crescere fino a 20 cm quindi consigliamo un litraggio di almeno 50 litri ad esemplare, altrimenti potrebbe svilupparsi male, o addirittura scontrarsi con altri simili o pesci che invadono zone del suo livello. La differenza tra maschio e femmina poò essere notata da due particolari, Il maschio partendo dalla coda vicino all' attaccatura delle zampe, presenta due piccole escrescenze, mentre la femmina all'attaccatura delle terze zampe presenta due piccoli fori. Il gambero Cherax è un predatore onnivoro.
