So I just went and purchased 5 what Were labelled as pygmy corys to go with my other 3 in the 17.5g. I have a good look in the car and they look like dwarf ottos! How do I know if they are dwarfs and not regular ottos? I don't mind keeping them if they are dwarfs since they should be fine in my tank.
