Blue Mexican Shrimp
I first discovered these prawns from a breeder in Germany. I imported them knowing very little about them but thought I would give it a shot. This is what I discovered. Basically in appearances they are very similar to the Macrobrachium dayanum (red claw). There are 2 major differences in appearance the first is there size, they are much smaller in size compared to that of the red claw. Secondly, probably the coolest difference and the reason I was drawn to them was the brilliant blue color of the males claws. Unlike the red claw the Mexican blue male has the ablility to change the color of his claws when sexually aroused or defending his territory from another male. At a relaxed state the claws are a reddish brown and blue at the joints. When he becomes excited or aroused his claws will flush a bright blue.
Tank Requirements
It is best to keep in small heiroms no less then a 10 gal tank. With one male and several females. Provided there is enough hiding places for everyone. I keep a lot of leaf litter in the tank to provide a lot of hiding places for the off spring. They do well in a planted tank and do not seem to bother the plants. I use a sponge filter powered by air and standard lighting.
Breeding
Breeding takes place at approx. 6 months of age. The female is only receptive right after a molt. Once the sperm is transferred to the female eggs will be developed and carried under the tail. She will carry her eggs for approx. 6 wks before hatching. Once hatched the young are miniature versions of the adult.
Feeding
This type of prawn is a omnivore and has much of the same diet as the red claw and will eat almost any commercially prepared foods. They particully love frozen myis shrimp and other frozen foods that you would find prepared for carnivorous fish and coral. When the smells of those foods enter the water they will go into a feeding frenzy searching out those meaty substances. I also feed them earthworms that I have raised myself.
