Lettuce Nudibranch Care Facts

Care Level: Moderate
Temperament: Peaceful
Diet: Omnivore
Reef Safe: Yes
Minimum Tank Size: 10 Gallons
Max Size: 3 inches
The Lettuce Nudibranch, Elysia diomedea also known as the Lettuce Sea Slug, is a well-equipped algae eater that gets energy from the photosynthetic algae it consumes. They will even take the chlorophyll from the algae and incorporate it into its own tissue. Its body is green and wavy very closely resembling a leaf of lettuce. 
They are best housed in tanks with plenty of live rock and away from aggressive species. The Lettuce Nudibranch will rid your tank of unwanted algae while being a fascinating organism to watch. Unlike some other sea slugs, the Lettuce Nudibranch is not aggressive and not poisonous making it a risk-free addition to any tank. 

Received in good condition and looks great.

It was small but neat to watch move around. I saw him the first few days and haven’t saw him since.

Cool guy! Though I have a 200 gallon tank I haven't seen him in a few days I'm sure he's busy with over 200lbs of rock!

Ordered three, all alive and doing great a week later. They are very interesting to watch. They move slowly, but are always on the go! They are helping out with my algae situation.

The Lettuce is very cool. It moves around a lot and loves to eat algae which is perfect. I am very happy with this purchase.

Added a Lettuce Nudibranch last week from the site. The creature came in robust and very healthy and has taken well to the tank. He is not bothered by my Bicolor Angel nor any of my other creatures and the LNudi doesn't bother Corals. He is all over the tank cleaning and moves quickly enough and is entertaining.

This is the best algae eater I've ever had to clean my tank. It eats the brown + the green algae. My live rocks are cleaned, my glass has never looked this clean, unless I scraped it myself. The brown stuff on the glass is gone......I bought 4 for a 90gal tank. I'm buying 4 for just to keep it clean.

Nice addition to your tank. Eats algae and fun to watch moving in your tank. Other fish will not eatthem either, had one try when first intro into tank but spit it out.

I love these Nudibranch, bought 4 from saltwater fish and got them healthy, viberant and fast. A must have for saltwater tanks...
