HM~ I have a blood gourami, which is an orange color to red ant times, with a light blue fin on the top of his body. Does your gourami have a blue fin on top? If we have the same fish, maybe I could help. None of the gouramis I have seen in the
LFS have had any black spots. I have seen alot of other fish with black spots that make them look dirty, but I think It's just the way they were born. I've seen alot of electric yellow cichlids with black all over and many platty's also. Maybe if you had a pic to post, we could see it better. As long as the fish is hungry, behaving normal, and appears healthy, there is probably no reason to be concerned. Has he had this coloration since you got him or did it develop afterward? Let me know if he is doing o.
k. Sorry I couldn't be of any real help 8O
