If you can get them into a quarantine tank you can use Panacur (fenbendazole) to permanently erradicate them. Only problem is, since you had them in your fuge, any free swimming hydroids are already in your main system and it would have been for nothing.
<b><u>You cannot dose Panacur in your display tank</b></u>
It is available from 1800Petmeds, or even some pet stores/feed stores.

And if you get mad and decide to use a blowtorch (which many do) ALWAYS wear safety goggles and gloves.

I used a lighter on them, worked good.
