ok i have 2 common plec's and i have a cave in my tank and i think they are breeding cuz both of them was in the cave and my male was ontop of my female but my question is, is that how they breed?
They aren't very easy to breed. How big are they? Are sure they are L001? Are you sure they are male and female, it can be quite hard to tell the two apart. I'm sure you could get them to breed in large caves, but they are mud wall breeders if i remember right.
