Green Sea Lettuce Macroalgae

Green Sea Lettuce creates thin, flat sheets which are translucent and very beautiful. In time it may form a disc shaped holdfast. It can be grown in the aquarium but may be eaten by many species of fish, sea hares, and other invertebrates. It is usually kept in a refugium or algae tumbler under high light, and under such conditions it makes an excellent exporter of nitrates and phosphates. The harvested portions make a terrific treat for aquarium inhabitants.
