Cherax Boesemani Var. Red brick (Red Brick)


Origin: New Guinea - Irian Jaya.
Appearance: Beautiful crayfish with bordeaux-red and pink colours. The body is usually red-brown and has pink to black shades. The claws are pink to purple-blue. Another variant is the blue one with the name Cherax sp. "blue brick".
Sexing: The male genitals can be found at the top of the 5th (last) pair of walking legs and for the females at the top of the 3rd walking legs. The female's claws are smaller and they are paler. White spots can often be seen on the outside of the walking legs of the males.
Life span: Unknown.
Size: 15cm.
Sexually mature: From 9 months.
Gestation: 30 to 50 days.
Character: Friendly towards fish although they like to eat fish. To many males can lead to fights. They can be kept in community tanks but be aware of the fact that they can dig.
Tank setup: Setup a special tank for these crayfish and add some fast fish. Use a tank from 80cm containing stones and roots. They like to dig and love fresh water.
Waterconditions: Temperature 18-28ÂșC, an acidity of pH6.8 to pH8.0 where the water hardness seems not to be important.
Feeding: Will eat nearly everything. Detritus, dead fish, small snails, dead plants and special crayfish food. Likes leaves of oak, alder and beech.
Breeding: Easy. The young grow slowly. Use lots of leaves and hiding places for the young because otherwise they will eat eachother. The colours will become more intense as they grow older.
Tank mates: Fast swimming fish and shrimp.
