Blue Knight Lobster

Cherax Quadricarinatus

The Blue Knight Lobster is from the rivers and streams of New Guinea, and is one of the larger species of crayfish attaining a total length of up to 20 cm. Their colors can vary from a brilliant blue to a bluish brown coloration, and they have relatively small claws for their size. They will rarely hunt for fish as they are generally too slow to catch the latter.

Provide a freshwater aquarium of at least 200 litre with plenty of rocks, and a substrate with a moderate grain size or finer for the Blue Knight Lobster to burrow in. They can be aggressive towards their own kind, and require plenty of room for territories, and a larger aquarium will be needed if housing more than one. When housing more than one, provide at least 40 litres per Lobster and include plenty of cover including both rocks and plants.

It is very difficult to differentiate between the sexes of these crayfish, and we will not be able to pair them for sale. They are relatively easy to breed in captivity, and the eggs hatch in about 21 days. After hatching, the fry can be fed flake or pellet foods, and should be separated in order to keep them from eating each other.

These Lobsters are omnivorous, and will act as a scavenger in the aquarium, eating any food that comes to rest on the bottom. Supplement their diet with a quality sinking pellet, flake food and dried algae.

Approximate Purchase Size: Medium 6cm - 8cm, Large 12cm - 15cm
