Fishy Update,
Had confirmation that the worms are either planaria or nemetones!!
Had started to do water changes and oddly the nitrate went up! Contacted the local fish specialists and they said we are doomed in the general area as the nitrate in the tap water is up and down on daily basis, he has clocked his recently from the tap at 180 mmol! He said of recent they have had to use treatment in the tanks and certainly the symptoms my fish show are identical to the symptoms his fish do when the nitrate goes up. He also added that because of something Anglian water add to the general supply, the lead in the pipes gets into our water supply and can cause poisoning. There is no doubt that I have defo over fed the fish and i have promptly rectified this but it seems I was on a loosing streak anyhow.
I have a 3 day course of Amquel to use to slowly reduce the nitrate and then just use this to treat the tap water before water changes. I asked about ro water and he said they have stopped recommending it for tropical fish and only use it for marine now due to it knocking valuable things out of the water!
Hope this may help someone else, since I added the treatment there have been no deaths, breathing has slowed slightly and the nitrate reading has dropped down slowly!!
thanks again for advice,
from the neurotic woman typing furiously last night ha ha!!!!
