this isnt the best pic. but the other three look like this one varying in size. im pretty sure they are male. still have alot of spangles and no blue or black on dorsal. the only time the dorsal gets dark is when they stripe up which doesnt mean female cause ive seen plenty of males that can look female minus the red on body but they wont start peeling for another inch at least. i have a 5th one that im treating for popeye that im sure is female;lacking spangles on fins, dorsal tends to stay dark but nothing definate and could be just stress from healing. i would take a pic of her but the tank is old and has scratches.
