Flag Fish owners - Give me some help please
I bought 6 juvenile American Flags about 2 weeks ago, and they're healthy and happy in their 15 gallon quarantine/nursery. They are all in the 1" range, give or take a mm or two. They also appear to be all females.. Is it too early to differentiate them sexually though? I see 2 of them in what looks to me to be a mating dance occasionally, with one passing the other and then stopping, and hugging close while backing up to stay abreast. The reason I think they're all females is because they have the colored dot on their dorsal fins, and except for 1 or 2 that have a checkered pattern, are all the same greenish grey.
Thanks for any insight you can give me into these fascinating fish!
