i was on the A19 near middlesborough thgis morning when i received a call from my son saying the following............'his water has gone cloudy overnight, and one of his clown loaches has died with what appeared to be cotton wool/spiders web kinda material over/on its mouth. so he has transferred his 2 remaining clowns, 2 hoplo cats, and 2 sailfin plecs into my tank
' 'thanks son
' was part of my reply.
so i now have an overstocked tank, with possibly ill/diseased fish in it. yesterday i did a water change in my tank, around 20%. i got a bit giddy. when i arrived home, not too long ago, i did another water change in my overstocked tank of around 30%. my sons tank is still very cloudy with no water change as yet, he went to work.
could someone please advize on best steps forward. i have no level readings as we do not have a test kit. i was about to go and do a 50% change for him but have decided to wait for feedback off here.
thank you,
mick.

cotton mouth disease seems the most likely, and tomorrow i will start the water changes in his tank and deal with mine as i see fit when i view mine again tomorrow.
