Sounds like anchor worm. Have a look at the picture at the top left on this
page -
http://users.megapathdsl.net/~solo/p...ics.htm#lernea and
see if this is what the strands looks like. If this is what you are dealing
with then you can pull the worms out with tweezers and treat with a med
which kills any lurking elsewhere in the tank.The meds which treat this are
pretty strong though and might kill off your bio-bugs too so test your water
regularly throughout and after treatment.

My goldfish are recovering from what I diagnosed as a bacterial infection
(did water changes and medicated with Tetracycline (recommended by LFS)),
but now there's some growth from where the red spots were before. Is this
normal? I took a closer look at the growth (kinda looks like a strand of
hair) and was wondering if i should try and remove it or leave it alone.
The fish are very active and don't seem bothered by the growth.
