Guest Posted July 12, 2021 Share Posted July 12, 2021 Hey all. I purchased a group of 6 baby rainbows about five weeks ago. They have since grown to about 1 inch and they all look female. At what age can you sex Furcata Rainbows? I am looking to breed them in my 29 gallon and I am considering getting more to make sure there is at least two males in my tank. Thanks in advance!

I did some research on my own and came across that article. It doesn't fully answer my question of when baby rainbows become old enough to tell the males and females apart. I decided to just play it safe and get more rainbows at my LFS. Thanks! Link to comment Share on other sites More sharing options...
Novabound Posted July 15, 2021 Share Posted July 15, 2021 I accidentally bred them once and it was a good amount of time before i could even tell they existed. I fed them fry food heavily every day to help the grow and i think it was like 5 or 6 months before i could start distinguishing between male and female. But they were sooooo tiny lol.
