Awe a big congrats ! , always fun to see new little baby cory's start coming out on their own accord in the main tank.....until you realise your basically going to have to dismantle the tank later if you need to get the young ones out for any reason.
I have been spotting the odd egg in different places in my cory tank, I have ruled out more peppered eggs because they are usually just one or two eggs (my peppereds usually put at least 4 per laying pozzie), the eggs are quite small and have been placed in spots that my peppereds wouldn't normally put eggs.
Some of these eggs have since hatched and the fry should be somewhere in the tank, so now it's a waiting game to see if it's the C. harborsus, some early breeding attempts buy the Brochis splendens, or hope against hope my 2 little many spots have finally done the deed. Ooops forgot about the false julii it they could even be the ones laying the eggs.
