Hammers Cobalt Blue Lobster: Care, Size, Color & Feeding

A Hammers Cobalt Blue Lobster can be a beautiful addition to an aquarium provided the circumstances are right. The colors of this aquarium crayfish can grow more vibrant over time, and they look great against a black background and black gravel.

Feeding Hammers Cobalt Blue Lobster

Hammers Cobalt Blue Lobsters are not fussy eaters. They are great scavengers 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 tank mates. Even though they will eat dead tank mates, its 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.

All other things being equal, the tighter the space, the more aggressive they can be.
