So I got 6 cherry barbs, 2 males (uncertain), and 4 females. I took some pics of the 2 males. I know the difference is obvious but one of the male in questions isn't as cherry colored. At most he is half cherry but I still question it.
The first picture is a definitive male. The second picture is the male in question. The third picture shows the 2 males following each other with a female behind (the second fish is the male in question in this picture).
