Most likely pale after he died.
On medications do not use ones with copper,malachite green, or any other of the such. Go with the salt method. Raise your temperature up to 84 (gradually!). This speeds up the ich's life span, which makes it die quicker. Start adding salt(again gradually!) until 2 tsp per gallon is achieved. After that you must watch carefully. When you do water changes you must replace the salt. Keep this up for about 2 weeks at a level of 2 tsp of salt per gallon, and a combination of high temperatures, you should be rid of ich in no time. Note that cories do not do well with this treatment at all. So if you have cories in the tank do not try it, or move the clown loach into a different tank or move the cories. Also if you have live plants salt will affect their growth, so if you do use a hospital tank would be alot easier.
Ich is in all fish when you think about it. Are these fish new? Most of the time ich is caused by poor water conditions or stress... is this a new tank?What are you keeping them in with? Any stress or new things done to this tank lately? If you treat them they should be fine, just be patient and keep up with the treatment.
Anyway Good luck with the ich,
