I have their 10 gal tank next to my desk so I was lucky enough to notice when the breeding frenzy started. I can see 3 eggs right now. One in the glass and 2 on Moss. From what I saw most eggs were being deposited in the underside of the Ludwigia Repens leafs. I wasn't expecting this at all, if anything I had just bought two grindal cultures to condition them. As far as I know Pygmaeus doesn't eat their own eggs/fry. I have an Otocinclus in there tho so I don't know what to expect. I am keeping him well fed with tilapia and veggies so hopefully he won't eat my grandsons. My tank is packed with leaf litter, you can only see plants and leafs, no substrate. The plan is for the fry to live off the infusoria. After I saw the corydoras breeding I boiled a handful of guava leafs to quickly get the tanins out. I added that water into the tank. I did it over the course of a few hours as to not shock anything. Now the tank is literally dark brown. I hope the tanins will help me avoid fungus. I have video of the corydoras doing the T-position, holding the eggs between their fins and cleaning a leaf and depositing them on the leafs. But for now here is a picture of a pair doing the T-position. Only time will tell wether they are fertile (I think they are, but the possibility that they aren't exists...) and wether there is any predation and the fry make it.
