Bad News@#$
I've found another fish (cobra guppy) with a large white spot around its eye. I have another cobra without this spot. This time I am pretty sure its unmistakeable. The cobra is the newer fish - perhaps it was the carrier?
I have quarentined these two fish and put a pill of Mardel Maracyn in the water. Is this the correct medication? Also, what about my original tank? Should I treat this. I am a bit hesitant to do this as I have very recently added some discus.
Thanks again for the help,
