Chances are, if you are reading this article, you already know what a Bristle Worm is and why you may need to "trap" it. But in case you are not quite sure ....
Bristle worms are free-living segmented worms with an elongated body that has a pair of "appendages" as well as tufts of bristles (hence the name) on each segment of its body.

These critters can vary A LOT in terms of size and color. They can usually be found living on or in the aquarium substrate and live rock. They like to move around at night, so go looking after dark with a flashlight ....
They might also show themselves when the tank is being fed.
This guys can be a problem for reef keepers, and can cause headaches when they get particularly large. (And they can grow quickly!) They feed on all sorts of things ...
For those who have one of these hungry guys and who want to get them out of your tank, Cromag08 has come up with what he calls a "Super Easy DIY Bristle Worm Trap"
Here's what you need in terms of Materials:
- small plastic beverage bottle (rigid is better)
- box cutter/razor blade
(remaining photos courtesy of Cromag08)
Wash out the bottle really well and take off any packaging material.
Use the razor blade to cut three "X"s evenly spaced along one side of the bottle.
Use your scissors to cut out holes. You want the holes so that your straws will fit snug.
Now cut three holes in the opposite side. These new holes should not be exactly straight across from the first row of holes, but rather a little closer. the final photo will show why this is.
Cut the straws and insert them into the holes.
Note: You want all of the straws to touch the sand, that is why the second row of holes need to be offset a little and not straight across from the first row.
Put some meaty food inside, place the trap in your tank with the lid on and make sure the straws are near the sand. Leave it in your tank overnight.
The next morning, check your trap and marvel at the glorious beauty of the bristle worm!
