Not the best picture possible, but i believe i have total 2 male Red Gold’s and one female, with the female being pictured here. I purchased a separation net, just in case and shes doing fine.
Signs that show this may be true
- Other fish were following her around, poking at her
- Red bottom area, getting darker
- More of a “boxy” stomach area
Do you keep live plants in your tank? I never had to worry as long as the plant coverage was good enough to break up lines of sight and allow fish to escape or hide. Guppy grass (Najas guadalupensis) and hornwort (Ceratophyllum demersum) were both excellent for this because they grow fast, don’t need to be anchored in the substrate, and are cheap and easy to come by. (They’re not ideal if you want your tank to keep a particular look with minimal effort, though. They can grow fast enough that you’re constantly pulling some out of your tank.)
I do not, but now I have more information to look up and soak in. :)
