Praecox Rainbows
 

I have a quick question. Just added 4 Praecox to my tank, they all appear to have the same coloration on their body as well as their fins (reddish orange). I tried to find a picture online of a male vs a female and haven't had much luck.

They appear to "school" together most of the time. They do raise their dorsal fins from time to time and circle each other. I have seen them nip at each other as well. I think that I may have gotten 4 males, and to be honest at the LFS they all appeared to be the same coloration as the ones that I bought.

If they are all males will they be ok? Is there anything other than fin color that will differentiate between the sexes?

I do, I will upload them tonight after I see if they are clear.

ditto on the coloration. its a fairly obvious difference so if they all look the same they all are the same. Having all males though isn't a problem at all however. I've had the same group of 5 males for months now just waiting for me to set up another tank and get some females.

Here are the pics that I have gotten that are viewable.

Here's the full tank pretty much with the group of 4 Praecox.

Here's some of them in one part of the Alternanthera Reineckii.

A single Rainbow. I think you can see one of my Honey Gouramis at the very bottom.

All 4 of them look identical to me.

Me too

Really? I would have said male. All of the female praecox I've ever kept had outright yellow fins rather than orange and those looks red-orange to me which would indicate male. The habit mentioned of them flashing their fins at one another would also indicate them to be males. Either way though groups of either all males or all females aren't a problem.
