Why is one of my male electric yellow cichlids so much smaller than the other male one?

Question

I have 2 electric yellows and I just finally realized the smaller electric yellow is a male because his bottom and rear fin has black color.....before this week it didn't show the color.

my other yellow is also a male.....but is so much BIGGER than him, yet i got these BOTH at the SAME time and SAME size!

i kept thinking that the smaller one must have been a female, since females are generally smaller then males, until i found out today hes a male as well....and hes barely growing. when i feed them they both eat every time too and theres absolutely no bullying, fighting, their black top fin is as black as black can be.

so my question is, how come? how could this yellow be growing so slow.

picture quality not great but these are the two

thank you for your time!

Answer 1

It's either that the bigger one dominates the smaller male if it is a male as well, or it is really a female
another distinctive mark i found on my yellows, is that the male has a false eggspot on the analfin
Just because the smaller one has some black on the ventral and analfin, doesn't necessarely mean it's a male




Hope that helps
Good luck
