Yes theyre a large species for sure. Couple females sitting at 3" markNice video, those corydoras eques are big guys, pretty and happy.
Is it a light green one or the reddish sword?What is the plant in front that is right in the middle of the tank?
It's starting to go red and it has in the past, it's just bouncing back after being shaded out in its previous tank and then adapting to being moved.No doubt I was turning to see Persicaria sao paulo, I see that it turns red although yours in green looks quite good.
