Take a common plastic beverage bottle(20 oz,1litre,2litre etc)
1.)Cut the top of it off right when it starts to form the neck of the bottle
2.) Reverse the piece you cut off so that the top of the bottle(part with the cap) is now facing into the beverage container
3.) glue the piece you cut off this way(superglue,hotglue, etc)
4.) place food into the trap(small pieces of shrimp,squid,fish etc work)
5.) place trap into tank over night(if left out over 24hrs you may get a fish stuck in it, so over night is recommended)
- if you find the container is holding air which is causing it to float just cut a small slit in the top to allow the air out, or weigh the bottle down with sand by pouring it into the bottle.
This is an effective trap and if done correctly will catch just about anything. Just keep in mind you may get more than the bristleworm
and though it doesn't take very many attempts to catch the intended target it could be a few nights before it yields.
