Show me the guppies!

Ok, so here's the tank which has been placed right outside the main door to our house. It's separated into two tanks, one for males and one for females (and the winning *prettiest* male). I still have yet to choose which male to put in there, I have a few candidates and am auditioning all of them for healthiest movement, color, and tail type.Here's the side for the females. It has a water sprite plant for the ones who are already pregnant and would be giving birth. This plant will give some of the fry a chance not to get eaten by the adults before I harvest and place them in a separate, smaller fry tank.
Here's the side for the males. It has two plants, a driftwood and some corals. Most of the time, the males stay near the surface feeding or playing with the bubbles from the pump.
Like so.
The following are solo pictures. This one's a female. She doesn't have a gonopodium (penis) on her belly side.
Unlike these next four gentlefish... This one's a lyretail, I think. His tail is divided into two. Pretty heavy it looks like- he often swims not as straight as the other males.
Like this red-tailed one.
Or this pink male.
Or this one with snake-scales-like-patterns on his body.
We currently have fifteen fry in the small tank. Hopefully they grow up nice looking males and get some new virgin females too. Hopefully they live past their first month- it's like Project Runway with these fishes... One day you're in the tank alive, the next day, you're out dead. :)
