Christmas Tree Worm on Rock, Multicolor - Live Aquaria
In what may be the most unique example of holiday spirit yet, a tank of electric eels powers a Christmas tree display at an aquarium in Japan.
Adventure Aquarium’s Christmas Celebration will feature larger-than-life decorations, twinkling lights, glowing trees, and gently falling snow — not to mention 8,500 super cool animals and two million gallons of fun.
Encrusting species of Porites, like the Boulder Coral, often enter the aquarium trade on live rock, or as a Christmas Tree Worm Rock. They come in many attractive colors including green, blue, golden yellow, yellow, purple, and pink. These colors can be very vivid, and for many specimens the color will be brought out under high intensity lighting.

As I said above, most small tube worms feed on phytoplankton, but the very large species, such as spp., tend to switch to consuming largely zooplankton as they grow – small animals feed primarily on small phytoplankton, but as the animal grows, so does the size of the mesh, and therefore the size of the phytoplankton preferred, and by the time the animal is an adult, these worms feed primarily on tiny zooplankton (rotifers, invertebrate larvae, copepods, etc.) but probably still capture large phytoplankton as well. The worms usually get enough suspended detritus and bacterial aggregates to grow when they are small, but as the animals mature and require larger plankton, the supply in most aquaria is quite limited, and specific feeding becomes ever more important. This is why many people observe that a worm initially does well in their tank, but as it grows it seems to languish and eventually suffer in the aquarium after long periods of apparently thriving. Feeding a variety of phytoplankton to small worms will obviously benefit them, but as they grow, the larger organic particles they will want in their diet. The Christmas Tree Worms, are an intermediate sized worm, and in the lab they appear to feed primarily on detrital floc, phytoplankton and ciliates. However, feeding preferences and strategies likely vary among species, and there are very few studies examining the natural diet of these worms. In the absence of such studies, we have only distributional studies suggesting that certain particle sizes or abundances are appropriate for certain species of Christmas Tree Worms. For example, some species, such as ain thrive only in highly turbid water with high organic particle counts of intermediate size; whereas others, such as are never found in such habitats and only thrive in areas characterized by clear water with relatively few tiny organic particles (Frank and Ten 1992).The Christmas moss (Vesicularia montagnei) was described by Broth. It belongs to the family Hypnaceae under order Hypnales of class Bryopsida. The mature frond hangs down and overlaps each other like the branches of a Christmas tree which give the common name ‘Christmas mosses’. Many aquarium hobbyists grow these plants as a moss wall for decorating the aquascape of fish tank. Synonym of this species is Hypnum montagnei Schimp. (1842).
