Sexing Cryptoheros Panamensis

  • We are currently upgrading MFK. thanks! -neo
Usually the females are much smaller, it's lucky to have a similar sized one.
When mine spawned they were very young, the female was only @ 2", male 4".
The fry are very much smaller than their cousins cutteri, mine seemed too small for artemia naupli.
 
Looks to me like pre-spawning jousting. The one on the right has a definite female coloration, much like mine did, and the darkening colors are similar to mine when they spawned.
