Thank you guys for your help here. I thought I'd try the temp thing but the thermometor seems to be one that only gets to 28* so there it is. I can't get into town till tomorrow to get more remedy but you can be sure I'll be hitting it hard when I do. IN the mean time no other fish have it yet and the rams, and the neons, apart from those horrid white spots, look full of life. There's no way I'll let this beat me, what a pain, now I realise the importance of a quaratine tank, I think I was very lucky with the fish shop in Masterton where they had a rigorous quarantine regulations and I never got anything bad from them.
