1 Australian Red Claw Crayfish 4-6 Inch Male, Freshwater Crayfish for Aquarium The Red Claw crayfish is a new and very promising aquaculture species. The Red Claw is very similar to the native American species, except that it grows to a HUGE size, almost to that of a lobster! This is a species with considerable potential for commercial culture. The features that made it suitable for aquaculture and the aquarium are its ability to withstand low oxygen levels and warm water associated with the tropics. Red claw lobsters are scavengers. They are a bottom dweller and will eat anything they come across, as they are opportunistic eaters. They will eat all of the left over food your fish miss, as well as detritus and other waste off the bottom of your aquarium. Although this lobster will eat dead or dying fish as well, it is normally too slow to catch healthy fish. Red Claw crayfish are easy and fun to raise in your tropical aquarium as unique pets. The redclaw is a valued aquarium species with their exotic coloration. They are less aggressive than most crayfish, and reproduce rapidly and easily.
