I recently purchased 2 Firemouths. The one has a reddish belly and seems pretty friendly. The other one doesn't appear to have any or very little red on it but is shy and hides a lot. That being said when he does come out it sees to be the boss and chases the other one. I read the red belly/neck is usually a male and the one with little color is female yet the one with little red color seems to be dominating as a male fish would be. Anyways I'll include some pics, sorry for them being blurry. Are they too young to determine their gender? Any guessers?

Coloration has nothing to do with sexing them.
I'd recommend getting a few more& letting them pair naturally

Thank you both for your replies. I never seen them in any of our store before until now and I bought the last 2. I asked the day I bought them if they would be getting anymore in but they were unsure. How can you tell then their gender if its not by color? I read by color then I read by fins. Even if they are young and you can give me advice so I can know what to look for as they age.
 
Best way to tell with firemouths is venting . Males and females are very similar in color and markings. So from one persons experence wont be the same as yours cause the fish variey. One thing I can say about their color is sometimes the male are a darker red and the are orangeish red again thats my experience.

Males tend to get longer faces and bigger mouths as they get bigger and the fin extentions tend to be longer and thicker ;)

Colors are much the same but I've also noticed the younger males tend to be more boisterous which can be an earlier indicator of the sexes
