Squat Lobster – Allogalathea elegans
The Squat Lobster, Allogalathea elegans, is a tiny and highly unusual marine crustacean with elegant striped markings, long slender claws and a close natural association with feather stars. Also known as the Crinoid Squat Lobster, Feather Star Squat Lobster or Elegant Squat Lobster, this Indo-Pacific species is not a true lobster, but a small anomuran crustacean more closely related to hermit crabs and porcelain crabs. It is reef safe with caution, peaceful and fascinating, but best suited to mature, calm reef aquariums where its delicate size and specialist feeding needs can be supported.

The Squat Lobster arrived healthy and active. It’s very interesting to watch as it moves around the feather stars in the tank. Feeding it daily with frozen copepods keeps it lively. It’s a great addition to a mature reef setup.

We’ve had this species for three months now. It’s peaceful and doesn’t cause any issues with the coral. Only needs a bit of effort in feeding, but the unique appearance makes it a highlight in our tank.

The detail in its striped pattern is stunning. It’s a rare and fascinating creature. We keep it in a 120-gallon tank with stable water parameters. It’s active during the day and hides at night.
