Not like other worms and not recommended for beginners featured

Comments Probably the most important thing to mention about this worm is that it is a commensal species, meaning it has a relationship with a coral, in this case, porite. The worm burrows into one of the porite heads and makes its home there. Without the porite, the worms dies. So an aquarist not only has to meet the needs of the worm, but the porite coral as well. Porite is a small polyp stony coral with its own light, clean water, and calcium requirements to be met. If the porite dies the worms will persist for a month or two, after which they will dwindle in numbers until they are all gone. If the porite is kept alive you can expect even more worms to show up as they reproduce. Another headache aquarists often run across with the porite rock is that they are often larger, baseball shaped rocks that are difficult to place in the aquarium and tend not to blend in to our carefully created aquascapes. I took a hammer and chisel to my two rocks. I lost a few worms in the process, but the overall result was worth it and they soon reproduced.

The worm itself is a filter feeder and will require either a mature tank, or to be fed phytoplankton depending on your set up. They need a constant moderate flow to facilitate their filter feeding but do not do well in high flow. Nor do they do well in high light conditions. Lighting should be just what the porite needs to survive, and nothing more.

This is my favorite of the worms, and what I consider the most attractive. It comes in a variety of colors, red, blue, green, yellow, white, gray, and black, are all very common on the same porite rock. The worms are light reactive, so passing your hand over top of the tank, creating a shadow, will cause them to retract, after the shadow passes they will soon reemerge.


Liked about it 1. Very colorful.
2. Fun to watch retract and come out again with the wave of a hand.
3. Reproduce in your tank.


Didn't like 1. Come on a big ugly porite rock.
2. The porite must be kept alive to keep the colony of worms alive for long.

great addition to an established tank!!

Comments similar if not identical to the coco worm feather duster the xmas tree worm rock is a perfect addition to ones aquarium, it adds color in a decent size and it also adds life to the tank. i have one of this in a 50gal and unlike some corals, which add color to the tank, the xmas tree worm adds a sense of life to the tank that i dont get from corals only


Liked about it -color
-movement
-growth rate


Didn't like -not as hardy as some other coco worms
-sensitive to ph
-sensitive to flow
