Size of tank in gallons or litres.
How many fish and which type.
Can you post your water stats please.

The string from the gills did it look like a parasite with a forked tail.
Or did it look like a string of cotton.

 

[beechey]

tank 90 gallon
fish with 8 discus 3 clowns i common plec 2 densil barbs and a few hatchet fish

stats are all zero ph 6.4 kn 3 gh 10

not sure about a fork as i said it was only about 3mm

Rare to have a nitrate reading of 0.
Whats your tap nitrate reading, do you have live plants in the tank.
Strands can be columarnis to parasites.
Anchor worm can look like cotton with a forked tail.
Was the fish flicking and rubbing.
Any red pierce marks on other fish.

Look under anchor worm and columnaris.

sorry nitrate is 100, i know water is good as the discus are breeding

rest of fish seem fine

A nitrate reading of 100 nots good then when it start to become harmful.
Whats your tap nitrate reading.
How often do you do a gravel vac and water change.
When did you last squeeze one of your filter sponges in tank water.

 

[beechey]

gravel vac and 40% every 5 days
tap nitrate never tested it!!
filter was done about 2 months ago...

If your tanks filter sponges are really mucked up squeeze one slightly in tank water.
Only touch one as you do the others in a week or fortnight time.
Do a test on your tap water.
