I think that a thread detailing this is long, LONG overdue... I vote clear photos from several angles and possibly some colour diagrams as well. I'd be happy to do the diagrams but I don't have all species of livebearers to take photographs of.
It might also be a good idea to do some clear colour photographs and also diagrams of how to sex each species of livebearer - it's pretty easy but instead of us all digging up photos every time somebody asks it would be good just to be able to direct them to a thread.
As I see it here's what we need for each species:
Each photo should be given from front, side and top. Multiples are good and it would be great if we had a run of photos of the same fish.
A photo of a fish that is not pregnant or has just given birth, to show the normal shape of a well fed fish's abdomen.
One week gone, just starting to show pregnancy.
Half term - lots of people are convinced by now that their fish is overdue.
Three weeks gone
Two or three days out - should show the beginnings of squaring off, and possibly the onset of 'broody' behavior.
Immediately before the birth - like those great photos 5teady got of his platy right before it bust. We should also commandeer that photo of the guppy he has - she's small, which shows that 'very pregnant' does not necessarily equate with 'hugely swollen abdomen'. We've also got to link to that thread about how to tell when she's ready to drop, and I might write something about trapping as well as we get a LOT of questions about that.
So did I leave anything out/stuff something up? no thread hijack intended, I'm just surprised that this hasn't been more positively received, I think it's definitely a necessary pinned thread.
