The Lettuce Nudibranch is a very interesting and useful creature. It helps tackling the unnecessary growth of algae. The Lettuce Nudibranch is photosynthetic in nature, and gets benefits from the chloroplast in their tissue from the algae they eat. It sucks in the chlorophyll contents of algae, and then incorporates that chlorophyll into their own tissues. It belongs to the family Elysiidae. The Lettuce Nudibranch is closely reassembled to a lettuce leaf, which is why it is named the Lettuce Nudibranch. It reaches a maximum size of 3 inch and is very hardy. The Lettuce Nudibranch is passive in nature, and is more active during day time and less at night time. There are no distinctive features that differentiates male from, female. The reef tank should be maintained with 70-80 degrees Fahrenheit for the proper growth and development of the Lettuce Nudibranch. It is a bright green color with ruffles across its back. It has an elongated oval shaped body and due to presence of ruffles it increases its surface area in order to absorb more oxygen for respiration. The Lettuce Nudibranch destroys and eliminates the growth of algae by foraging on live rocks and aquarium glass. Thus, it helps keeping the environment clean and clear. It is non venomous and a very hardy species, which makes it a terrific addition to any reef tanks. The aquarium needs to have some live rocks which serve as a natural shelter for the Lettuce Nudibranch. They belong to Gastropods class who are snail like creature and do not possess any shell for their protection. The Lettuce Nudibranch is very peace loving and gets along with other inhabitants. It surely makes the aquarium more attractive with its interesting appearance and function.
Great addition
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...

The Lettuce Nudibranch, a.k.a The Lettuce Leaf Nudibranch, is bright green in color with ruffles across its back. It is excellent at destroying algae by foraging on live rock and aquarium glass. It is non-venomous and a hardy species.Sea Slugs are part of a Class of Mollusks known as Gastropods. These snail-like creatures do not use a shell for protection. Most Sea Slugs are a shade of green and have an elongated oval shaped body. These creatures usually have ruffled backs which uses increased surface area in order to absorb oxygen for respiration. At the head are tentacles that appear to be "rolled". Sea Slugs are algae eaters.Photo by member, Eric Stein.
