StaceyTNBCkicker Posted November 10, 2020 Share Posted November 10, 2020 I bought my drawf neon rainbow fish from a LFS. I purposely bought 2 males (red fins) and 4 females (yellow fins) striving to have a more balanced group. The 2 males dance and flare for the females and get a "breeding stripe" of yellow on their backs. This morning, I noticed one of the yellow tailed "females" dancing and has a "breeding stripe" as well. Do the females get this as they mature? Or is a male in female colors? Thank you for any advice! Link to comment Share on other sites More sharing options...
Andrew Geiger Posted November 13, 2020 Share Posted November 13, 2020 Ive never had rainbows, so take this as a grain of salt. But I would bet that if its behaving like a male that it is a male, you'll find out when they go gravid with eggs which are which. Alot of subdominant males will have less color, also I know that some egg scattering fish have early maturing males that wont have good color and sometimes smaller in size too. 1 Link to comment Share on other sites More sharing options...
