The top (dorsal?) fin on one of my neon tetras is a cloudy white instead of clear like the rest. It's extremely hard to tell, but sometimes it looks like it might be dimensional (i.e., it's not just cloudy but cloudy with something sticking out) while other times it looks like it's just cloudy.
Anyone experience something like this? It doesn't really look like ich. Maybe a fungus?
