[stephane]

Ick is alway present in you tank but mosly not on the fish it stay in the water colum

I have 3 tang in my 130 for severale years it's been a long time since I have not buy a new fish an last summer when I move my tank all fish that where there for severale years caught the ick due to the stess and temperature fluctuation

The best medication I found is do noting but feed them and NEVER try to cath them for a quarantine it will only make it more sick and could even make the fish die because stress is a major factore in fish healt

Here I talk of a reef whith a good water quality if you have this you dont need anyting else
