https://www.vetnurse.co.uk/f/nonclinical-discussions/10251/goldfish-help We have 2 normal goldfish in a large tank which currently does not have a filter (due to the last one dying). The tank was fine yesterday morning when they were fed as I checked as normal, but evil and foul smelling last night.

I am always wary putting fish &#39;medicines&#39; into the water, from past experience it seems to kill rather than cure!</p> <p>Thank you both for your help, I will mail Kate now thanks Vicky!</p><div style="clear:both;"></div>https://www.vetnurse.co.uk/thread/94866?ContentTypeID=1Sun, 29 Aug 2010 13:25:14 GMT1a0763ec-3885-442c-853e-6cef656dfec5:f44c5162-241e-4c69-a458-56ad97680fe6Rachel Jayne<p>I had a similar problem with mine once, spoke to a family friend who is a bit of a fish-specialist who said it was an ammonia scald....which would explain the foul smell too.</p> <p>There are drops you can get to go in the water, but I can&#39;t remember what they&#39;re called. <br />They were dark blue, almost like a dye, but did the trick. </p> <p>Good luck! <img src="http://www.vetnurse.co.uk/emoticons/new/Fingerscrossed.png" alt="Fingers crossed" /></p><div style="clear:both;"></div>https://www.vetnurse.co.uk/thread/94850?ContentTypeID=1Sun, 29 Aug 2010 11:00:38 GMT1a0763ec-3885-442c-853e-6cef656dfec5:697da353-ff22-4c45-89d0-34041d6ba320Vicky RVN<p>Send Kate C a pm!</p><div style="clear:both;"></div>
