Hammers Cobalt Lobster

The Cobalt Hammers lobster was bred by a Mr. Hammer in Florida to get a cobalt blue body on a lobster that will not outgrow the fish tank and feature a less aggressive nature than other cherax species. He succeeded. Similar in color to the dwarf blue lobster, the Hammers Cobalt will grow to a larger size and actually gets more blue as it ages.

Quick Facts

Care Guide

Tank setup: Crayfish need plenty of hiding places like caves or pipes and a tight-fitting lid, since they climb out. Avoid copper-based medications.

Feeding: Feed sinking pellets once a day. They also eat vegetables and leftover food.

Tankmates: Crayfish will catch and eat slow fish, shrimp and snails. They are best kept alone.

Molting: Crayfish shed their shell to grow. Leave the old shell in the tank; they eat it to regain calcium.

Good to know: Hammers cobalt crayfish get bluer as they get older.
