I have 11 pygmy corys in my shrimp tank. (some from April and some from IPU.) and they usually just mind their own business or hide between plants. Today I notice something really small swim around rapidly and turn out it is baby pygmy cory! I didn't even know my pygmy cory have lay egg. It is small I have to put put a circle to show where it is. I wonder how many baby pygmy corys I have thou I probably won't know until I remvoe all the plants and carpet.
