Crinoid Squat Lobster
The Crinoid Squat Lobster is one of the most interesting nano-inverts to enter the hobby in recent years. They are peaceful and completely reef safe. The Crinoid Squat Lobster is very small, most reaching only up to 1-1/2″ or 2″ in size.
Common Squat Lobsters can sometimes be found as hitchhikers on live rock or corals and make fine pets, but these hitchhikers are normally dull colored. Crinoid Squat Lobsters such as the ones pictured above are becoming more common in the aquarium trade. In the wild, these crustaceans are commensal on Crinoid Feather Sea Stars. They use the sea stars for camouflage and steal their food.
Crinoid Feather Stars are one of the most difficult echinoderms to successfully maintain in aquariums. Luckily, these Crinoid Squat Lobsters do not require the same level of care and are well-suited for nano reef tanks.
| Size | Color | Behavior |
|---|---|---|
| 1.5″ – 2″ | Varies, often with vibrant patterns | Peaceful, non-aggressive, reef-safe |

I added a Crinoid Squat Lobster to my 10-gallon reef tank and it has been thriving. It’s small, active, and doesn’t bother any of the corals. The coloration is quite striking and it looks natural in the tank. Easy to care for and a great addition to a nano reef.

The lobster arrived healthy and has been active since setup. It doesn’t seem to interact with other tank mates, which is perfect for a reef tank. I appreciate that it’s reef-safe and doesn’t require special feeding.

This is one of the most interesting inverts I’ve kept. It’s peaceful, stays in one spot, and looks like it’s part of the natural environment. I didn’t expect it to be so colorful and active. Great for beginners looking for a low-maintenance nano pet.
