I was cleaning my tank when I noticed that there were a lot of tiny

before.
They have always been fed on pallets.

Any ideas on what the worms are? Are they harmful to fishes? Will
adding
0.03% salt kill them? I strongly belief that my canister filter is
also
infested with the worms (I am reluctant to throw away the filter medias
as
they are cycled)..

Any help is appreciated. Thanks

Am somewhat of a novice so appologies if i'm totally wrong. Are the
worms reddish in colour? If so, they could be small blood worms. I had
lots of them in my back garden pond last year. As far as I know, they
are harmless - in fact, they are somewhat of a delicacy to certain
tropical fish.

Have a look on the following website - shows some picture.

Sorry I can't be of any further help or if I'm totally off the mark.

they're very unlikely to be bloodworms unless there are
mosquito-type-things laying in your tank. I think the standard answer is
"planaria". They're harmless but a sign of overfeeding and uneaten food
collecting in your gravel. I'd cut back on your feeding a lot, gravel
vac every few days and see what happens.
