I believe they need a male. Hence why they make their T shaped breeding postures to inseminate the eggs. I'm still waiting for my Albinos to lay eggs but i've gotten eggs from my Pepper and Green corys growing up in a 5.5 gallon.
Ok so I definitely have a male right? Do you think there is a reason all the eggs fungussed over last time and they haven’t laid eggs since? I’m doing lots of cool water changes and really fattening them up, is there anything else I can do?
