Hi, as some might know 2 of my bronze corydoras died, now I am left with 6 cories. I would like to add 6 other cories but I don't know what specie... I would like a specie that could live with the bronze cories (pygmaeus couldn't for exemple right?) and that is small like around 2 inch also the specie really needs to be hardy not like panda cories (that's what I heard). The temperature in this tank is 25°c. Any ideas? Thanks
