Has the fish been digging in the substrate.
Can you issolate the fish.
Spots that have a circling or red on the ouside is bacterial columnaris.

Wounds that are white on the edges and red in the center are most typically Aeromonas. Those that are red on the edges and white in the center are generally Columnaris. Both are gram negative bacteria. The best treatment for this is any sulfa antibiotic with trimetheprim. This can be put in the water and mixed with food -- if you can find Romet B use it.
