help me .sex my vieja synspilum

  • We are currently upgrading MFK. thanks! -neo
I've been wondering about my syn too looks exactly like yours I think it's hard to tell at such a young age But what I have read is that the males are more colourful Longer finage and with age with develop a hump on its forehead I think mine is a female due to lack of extended finage Any help from anyone else on this forum would most helpful
 
Agree with duanes.
All the males I have had have developed blue eyes.
Also the dorsal fin rises towards the end.
In males this rises at a steeper angle than the female.
Unless you have both sexes side by side it's hard to see these differences. Males will also have a bigger built steeper cranial profile than a female once they reach about 6 or 7 inches.
