Antibiotics? updated, with pics of my sick fish

[Static]

Thanks for the info.

This fish has been in a 20 gallon quarantine tank since I purchased it 1 and a half weeks ago. And in that time I've done 5 gallon water changes every 2-3 days.

I set up this tank when my clown fish had some fin rot a couple months ago. I'm wondering now if I shouldn't have broken down the tank and sterilized everything, but with the use of the maracyn, (erythromycyn) my clownfish recovered and was healthy for several weeks befor I returned him to my display tank (although he is missing most of his dorsal fin).

Since maracyn 2, intended for gram- bacteria isn't available off the shelf anymore, should I just phone veterinarians and hope that I find one that is sympathetic to my situation. I believe that maracyn 2 is Minocycline.

You mention trisulfa drugs. Are these available in canada, I'm guessing not off the shelf.

My tank temp is currently 82, you mentioned raising the salinity... by how much?

Thanks again for your suggestions. I really wish I could help this fish
