Just noticed that my largest Clown Loach has a few dark, black spots on his dorsal fin and tail. Couldn't see any of this on the others, but he's acting perfectly normal... Eating like a pig and active. I can try to get some pictures tomorrow, but for now all I can do is describe them. Is there any sort of common disease that causes this? There are about 4 of them total, ranging from a small spec to a dot the size of a VERY small pea. Any input would be greatly appreciated.
Thanks
