thanks everyone,
I thought they are both males, but wasn't sure... the larger fish chases the other one, but nothing serious - doesn't try to kill him that was confusing
I can't identify the sex of the guy to the left on photo... the same fish is on the single pic...
(I'm pretty sure that the guy to the right is a male)
I've come from the other side of the globe (perchance, anyone from Kyrgyzstan? )
I've got 44 g tank, freshwater, never had saltwater, but admire those who can do it...
love convicts... going to have rams and severums
