Description : Characteristic shape of the shrimps belonging to the Caridina genus, short rostrum. This shrimp has a background colour based on three colours : orange, black and white. The intensity of the colours can vary a lot depending on the water specifications and/or the food.

A few variety exist :

	Caridina cf. cantonensis ‘Tiger’ The colour can range from brown to grey and to red, and even transparent. The body presents a few stripes (between 5 and 7) that are brown black. The females are often darker when bearing eggs.
	Caridina cf. cantonensis ‘Crystal Red’ White and red stripes (or black). The colour can be reinforced with carotene contained in the food. It was selected by Hisayasu Suzuki in the middle of the 90s (See the specific page)
	Caridina cf. Cantonensis ´Blue Tiger´ Deep blue to nearly white, striped, with clear coloured eyes (pink, orange or golden depending of the lighting).

Behaviour : Excellent gregarious, specie must absolutely live in groups of 6 individuals of the same specie no less.

Life span : Up to 18 months.

Feeding habits : Omnivorous it will be composed of flakes, algae, pellets, frozen food, live, vegetables…

Sexual dismorphism : As a general rule, female are larger than males. The segments making up the abdomen are lengthened towards the underside to offer protection to eggs that are held by the pleopods (swimmerets located under the abdomen). The antennules (shortest set of antenna) of the male are longer than those of the females. The cephalothorax is rounder in females (detail photographed on the male and the female).[1]

Reproduction : Simple, it doesn’t need any salt water larval stage. Every two to three weeks the female carries thirty eggs for an incubation period of four to six weeks. Stimulation can be improved by lowering the water temperature to 18 for a few weeks then bringing it gradually back to 25. The young are sexually mature after 4 months.
