Kengore,
I've had good luck with using hollow body tubing.
Pull the tailing material through the tubing, securing it with a drop of CA glue....I usually use either light mono or another synthetic so I can properly set the tails with a bit of heat.
I use a set of forceps to get the 'segmentation' look...heat the forcepts then crimp the tubing lengthwse in the jaws..I imagine that any tool with serated jaws would work...I use markers to add colors to both the body and the tails...pretty realistic looking, and they last all day....plus the air trapped in the tubing helps with floatation....
