I am not seeing the white spot is it on the fin ?
that just looks like some color loss but you could treat with food soaked in garlic to stimulate the appitite ....... there are foods with garlic in them and I hear kick ich works well in a reef tank , bu dont use copper based meds as it will wipe out the tank and also making it imposible in the future to house inverts .... sorry I couldnt help more :sad:
If it's ich you are gonna know because he will break out pretty bad and be scatching against the gravel or rocks; then if it's not treated you'll get a major loss of appetite.
I would use No-ich as it's getting more and more popular with the reefs and it works; I've used it twice.
You need to be sure it's ich before you run out and med your tank...
Nemo Mike hit it pretty well from the behaviours to what he uses in his 72 gallon .
In my humble and honest opinion I dont think that it is ich. Try to wipe the glass down to get a clearer pic that may help a bit :mrgreen:
I got rid of the clown. I also got rid of my 10G too many tanks, Took half my weekend to clean them. I was able to trade some live stock from that tank for some cool coral with local reefers.
