I have a pair of blue acaras that I got last week. At the store I bought them at, while watching them in the tank, I was pretty convinced that the two were an established pair. They were guarding a particular area of the tank and many of the other acaras in the tank were somewhat beat up. I was very deliberate in pointing out to the employee which two fish I wanted, and I watched him get the fish out. Now, having them in a tank at home, they appear to both be male. What is the best way to tell if this is true? From research I've done, the best way is supposedly to look at the anal and dorsal fins, both of which should be longer. Is there any other way? If I have two males, I need to take one back. Thanks for the help!
 
pics would help, but yea, easypeasy way to tell is dosal/anal fin length secondary (if you know their of smae or similar age is size, males tending much larger

heres two pics first is female, second is her partner
(excuse the red circles they were done for pointing out fry, old photo LOL)

The male in the pic is still youngish in this shot but you can see the greater angle in his fins compared to the females
 
OK better pic

the male (bottom) has much longer fins, also note the flowing filament that has devoped, his age is about 16months (from spawning), the female is only a little smaller but she is also his mother and is 6 months+ older than him, plus she was store bought so proller add at least another 3-4 months there.

Thanks for the pictures. My two acaras are pretty small, but I think they're both males, unfortunately. They're also quite camera shy, lol.
 
When not spawning do the females have better color? The first male seems to have good color compared to the female, dont know if thats just how they normally are.
 
actually when spawing their colour is better, shes washed out due to the camera flash (the obviousness of the vertical markings shows that she should have some some decent markings)
