General info about Hammers Cobalt Blue Lobster

The Hammers Cobalt Blue Lobster is one of the most striking ornamental crayfish you’ll ever see. It will add tankmates splash of brilliant blue color that’s sure to draw attention to your freshwater aquarium. The coloration of this blue beauty intensifies as it matures. They look great against a black background and black gravel. This species has been selectively bred for a number of years to produce the brilliant blue coloration that is commonly offered with the aquarium hobby today. Due to selective breeding, the Hammers Cobalt Blue Lobster will not lose this blue coloration, except in times of stress. 

In the wild, specimens of this species vary in color from a brown/tan color to a light blue to cobalt blue color. However, the specimens offered in the aquarium trade are chosen specifically for their blue coloration and while they may appear a light blue or tan during shipping or when first introduced into the aquarium, will quickly regain their brilliant blue coloration once they are feeling at home.

The blue coloration of the Cobalt Blue Lobster will darken as it matures going from a light blue color in young specimens to a brilliant cobalt blue color in mature specimens. While wild specimens can reach appreciably larger sizes, the selective breeding the produces the bright blue coloration also limits the adult size of the specimen, with the Cobalt Blue Lobster typically reaching only about 5 inches within the aquarium environment. At the store, Hammers Cobalt Blue Lobsters may be around 2 to 3 inches in length. Over time, they can grow to be about 5 inches. So it is necessary to provide enough bottom space for them to roam. The tank size required for each Hammers Cobalt Blue Lobster should have at least 20 gallons of water with medium or fine grain substrate for burrowing. Hammers Cobalt Blue Lobster also like plenty of rocks and caves to walk on and interesting hiding places to explore.

Hammers Cobalt Blue Lobster can be territorial and aggressive by nature. This is especially true with others of their kind. To house multiple lobsters, the larger aquarium will be needed; at least 20 gallons per lobster and include plenty of rocks and plants as cover. All other things being equal, the tighter space means the more aggressive they can be. While they are generally peaceful towards fish species and other invertebrates, they will eat fish that are very small and slow enough for the crayfish to catch. Providing the Cobalt Blue Lobster plenty of easy meals consisting of meat-based sinking pellets or algae wafers will help curb their aggression towards any fish living in the aquarium, as they will go for the easier meal.

Cobalt Blue Lobsters also tolerate a wide range of aquarium conditions including pH, GH, temperature and water quality and should do well in any reasonable aquarium setup. These lobsters can survive in tanks with pH levels of 6.5-8.5 and temperatures of 65-90° F.

Hammers Cobalt Blue Lobster Diet & Nutrition

Hammers Cobalt Blue Lobsters are not fussy eaters. These lobsters are omnivorous and will act as a scavenger in the aquarium and eat almost everything on the bottom of a tank. Their diet includes uneaten food, debris, detritus, live plants, dead plants, fish flakes, pellets, tablets, algae wafers, live tank mates and even dead tankmates. Even though they will eat dead tankmates, it is best to remove them from the tank to avoid water quality issues, as well as the spread of diseases. Finally, make sure they are getting Calcium in their diet. Calcium is important for molting and healthy shell growth. Their diet should be supplemented with a quality sinking pellet, flake food, and dried algae.

Breeding & Spawning Hammers Cobalt Blue Lobster

In general, the Cobalt Blue Lobster is very easy to breed in that they will readily breed in almost any conditions. However, they must be selectively bred to produce bright blue specimens, which take a considerable amount of effort and a fairly large scale breeding operation.
