I have found similar animals in my salt water (local) tank right after
loosing several healthy fish. I assumed they were some kind of parasite. I
have had them a few times after adding newly caught fish to a tank. I now
use a small isolation tank treated with copper and have not had them return.
If anyone knows exactly what they are I would like to know also.

We recently had some donated plants spend a night in an unused
aquarium. This afternoon we found some sort of brown worm ... it
seems to burrow in the gravel with one end and at times floats the
other end at the surface (as if breathing through it).

I can't say I've seen anything like this before (science fiction
movies aside, of course) and am wondering what this creature is and if
it's something that's better off dead than in a pond?

Thanks!
