My Ram started with one white spot and it seemed to have spread a bit in the course of about a month or two. No other fish has gotten these spots since I've seen them on my Ram. I'm wondering if this is ich or not? Can it possibly be any other type of fish disease? I'm guessing it were ich, wouldn't my other fish have them by now? Also, wouldn't it have spread throughout my Ram's body and not just the one area by the front (as shown in the picture below)?
If you guys think this is ich, which of the several methods out there are the best and safest?
I haven't introduced any new fish or plants in like 4 to 5 months. I don't have a quarantine tank so this will have to be the hospital tank (if need be). I have a Kuhli Loach which might be scaleless in there so I don't know how well he could take meds? Other inhabitants are Ottos, Pygmy Corries, Glow Fish (Zebra Danios), and Red Minor / Von Rio Tetras. Oh and my BB Goby. Lastly, I have some low light plants such as Swords, Java Fern, and Anubias.
Advice is much appreciated!
