I've had my 90 gallon tank set up for about 6 months and currently have 2 clowns, a red sea sailfin and a blue tang. Both the sailfin and the blue tang are juenvilles; about 4-7cm long.
When I got home from work today i discovered that my blue tang was covered in white ich spots
I have only had the blue tang for about 3 weeks, he seemed fine, he was eating nori and mysis shrimp and was swimming around happily. He wasnt scratching on rocks or anything.
I quickly set up a make shift QT; im upgrading to a 140 gallon in a few weeks and was planning to use my current tank as the QT but ich beat me to it!
My questions are:
1. The blue tang is already in the QT, do i need to put the sailfin and clowns in aswell? None of them are showing any signs of ich yet.
2. Whats the best way to treat it? I was thinking more of the natural ways, giving the fish a freshwater bath, raising the temp to around 80 degrees, or hypersalinity? However if the copper treatments are a lot more recommended and effective then I will use them.
Because the blue tang is so small Im worried that I have to act very quickly. Any suggestions would be greatly appreciated!
Oh and my water params are: Ph= 8.2, ammonia/nitrate= 0, nitrate=0, sg
