just curious what week i will be able to sex guppy fry (rough estimate)..... also another interesting note... the one guppy that gave birth seemed a bit early ...cuz she is a new add on to my tank and was only pregnant for like 3 weeks... but then again she only gave birth to 8 fry... so i guess that may be why... and i know she wasnt pregnant before i put her in there. my other female has been in a week longer and is still pregnant!!! awaiting her fry too
it will vary from fry to fry, but up until about the 4th or 5th week they should all look like females, the males will develope a longer anal fin while the females anal fin will remain triangular
Edit: Nevermind, posted this early in the morning, and didn't read the numbers right! For sexing Guppy fry, if you look very closely you should be able to sex them pretty soon....a month or so. Sometimes they can breed as early as 3 months, so the sooner you can seperate them, the better.
