Help with sick fish

[calihawker]

Hi.
I have a 3.5 inch discus that has stopped eating. It is one of 12 that I have had in a grow out tank for 3 weeks, every one else is doing fine. I don't see any obvious signs of illness. No lesions, no spots, I haven't seen any feces to examine. He just looks dark blue and hides in the back of the tank.

I would like to isolate him to examine him better and treat him but my qt tank is currently housing a dolphin mormyrid that I've had for just a few days and he's not ready for the display. Can I examine and treat the discus with the dolphin in the tank? Raise temps and maybe metro? Should I put the dolphin in with the other discus? I don't want to treat the grow out tank until I know whats going on.

Sorry I can't provide pics. My camera'a broke.

Thanks for your help.

Do not treat in the tank with the dolphin morymid, these are intolerant of virtually all meds we use, in particular dye based meds (MB, Acriflavine, F&MG, Copper.....) and they don't do good with salt either!!

Personally I wouldn't risk breaking QT either. Bit of a rock and hard place if you have no other tanks.

Two options, 1 is to do a salt dip, 3 tablespoons in a gallon of clean water and dip for 20 mins. Try and do a wipe down and w/c during this - but watch the fish in case it rolls. If it rolls remove immediately. The other is to use a shotgun med like quick cure in the grow out tank, follow dosing instructions.
