Hi Karen I know your post is a little old now and probably solved your problem already. Just wanted to let you know that that Bio-Elite. Heal all is a great product. Its all natural and this little chance of overdosing. I would suggest putting your discuss in a hospital tank and treating with this. They also have an anti ich treatment but I found the results on this a little slow. This does not however treat internal parasites, so if it is internal you will know sooner rather than later later. Oh and its safe for plants too. I did find a slight difference in my plants but nothing a little fert could not fix. Hope it went well with the recovery
