Overview

The Lettuce Sea Slug is an unusual and entertaining addition to the reef aquarium. It has highly folded parapodia (side appendages), which give it a ruffled appearance similar to lettuce. The Lettuce Sea Slug is captivating not only for its interesting shape but also for its purposeful and comical manner in which it creeps along your reef aquarium. The coloration of the Lettuce Sea Slug generally ranges from green, yellow, or brown.

The Lettuce Sea Slug may also be referred to as the Lettuce Nudibranch, or Green Lettuce Nudibranch, although it is not a true nudibranch. The Lettuce Sea Slug will do well in established aquarium systems, if provided ample room to forage. It prefers an aquarium with live rock so that it can graze on algae.

The Lettuce Sea Slug incorporates the chloroplasts (the portions of the cell responsible for photosynthesis) from the algae into its tissues, and thus relies on photosynthesis for part of its energy. Pump intakes and drains can harm the Lettuce Sea Slug, so care should be taken to screen these off. It is sensitive to high levels of nitrate and will not tolerate copper-based medications. The Lettuce Sea Slug has no distinguishing characteristics to help differentiate it from its mate.

Customer Testimonials

Carol J El Paso , TX
I really like this guy. He is all over the place. At first I was afraid he would get sucked into the powerhead case but he managed to avoid it. No one bothers him either.
Sherry K Hillsdale , WV
This animal is much more active than I thought he would be! He is always on the move, cleaning the glass and rocks. He leaves a gossamer trail of tiny bubbles everywhere he goes, but that's okay with me. The bubbles go away after a while. We're happy with this interesting and active critter.
Michael MA
I LOVE these little guys!!!! I have 4 in my 12 gallon nano reef. They are peaceful and they are very active!!! I highly, highly, highly recommend these things!!!! WARNING: If u do not like strange and bizarre things this is not for you! These are the most bizzare things! They change colors, shape, and size all the time. THESE NUDI'S ARE EXTREMELY AWESOME!!!
Eric H Chicago , IL
They look like slow movers but they are quick around the tank. My daughter enjoys the two I got for her. They are very interesting to look at and watch. One of them enjoys coming to the top of the tank. Than letting go to curl into a ball and let the movement of the water bring him to the bottom of the tank. Very fun to watch.
David McDonald Rock Island , TN
These little guys are awesome. I got two of them for my tank as part of my new clean up crew. Within a week my live rock looks like live rock now! They took care of the algae and are always on the move. Great asset to your clean up crew.
Dominic M Rancho Cucamonga , CA
These guys are the best! I bought two and after a few months of entertainment they disappeared. Then two weeks later I've found at least a dozen babies running around the tank. The babies are TINY and fun to watch!
Elizabeth S Mobile , AL
My lettuce sea slug was crawling around the bag when he arrived! After acclimated he started to zip around. He’s beautiful! Thanks Live Aquaria,
Cody Moederndorfer Mattawan , MI
