Question about Tiger Barbs
I have only had my new aquarium set up for about a week and I just noticed yesterday that 1 of the 3 Tiger Barbs I have has a very orange color at the end of its face. Think of a person with a cold that has a very red nose from blowing it so much.
I do not believe this was case case when I bought them a few days ago but could be wrong. Is it possible that the difference may be related to the sex of the fish?
