I have 3 sunset honey gouramis - one is obviously male (not pictured) and one I'm pretty sure is female (the one on the right in the first picture) and one I'm not sure about (the one on the left, and in the second picture). He/she used to have a more obvious stripe down the side, and has now developed a spot of darker color on the botton fin. He/she is not as colorful as my obvious male, not as bright yellow and doesn't have the dark throat. His/her coloration is in between the two others. Any ideas on the sex? Hope the pictures are clear enough.
