i know they are JDS but there are just so many different kinds. i also have some from the same batch that are almost black...very very dark stripes...and is the red on the dorsal fin tips mean its def male? do females just not have the red at all?

You identified them yourself. They're jack dempseys, aka Rocio octofasciatum. There's no other "species" of them, just one.

yeah some have the red on the tops of dorsal fins..im assuming those are the males.

 

[artemis1]

You can tell by the operculum (gill plate). On males there are several spots of blue, on females it's almost solid blue, or at least a lot more. Males also get larger and have longer fins.

do you know why the same fry would have some that are very light and some that are very dark..almost convict looking?

 

[artemis1]

just individual differences. not enough to be a different variety or something.

you'd know if you had an EBJD, the body would be a bright powder blue with black spots, or a gold jd (aka xanthic jd) where the body would be completely yellow.
