if its only 3in, then i think it may be a late blooming male, my guy didnt get pointed fins till he was 3.5in while my female got pointed fins and trailers at 2.5-3in so with that you never can tell, though if the body scales are nice and iridescent/shiny then its most likely male, best bet would be to catch him and vent him (or take pic of his/her vent under high lighting and post on here)Terrobite;3920351; said:Im going to say that he is about 3 inches long maybe grown 1 inch in 4 months.. the pictures I have given dont do it justice as i cant get a full side on picture without a flash as it always comes up blurry.. I will keep trying thanks all for you comments
