New colors and color combinations have been added to the collection.Silver moon is the smaller size fern in the collection. It is approximately 2.5" in length, with fluffy corraling at the head. This the problem: it's called FERN. Most people see a sea creature, perhaps a sea horse in the coral. Picture a coral laden wall and you're on a night dive. The gentle arms sway back and forth beckoning you to examine it (NO HANDS!) to see if something is staring out at you.
