Sexual dimorphism in c. trilineatus?
Posted: 21 Apr 2014, 18:27
Hi all
Just a quick question to check a theory/observation of mine. I have 5 cory trilineatus - 2 males and 3 females. They are all busy spawning at the moment and I don't know whether this affects things. However, I've noticed that my males all have very marked spots on their pelvic fins, whereas the girls have clear or almost clear pelvic fins.
Obviously, five is not enough to make a call on it, but wondered if anyone else had noticed that or had any ideas on it?
