my bronze cories spawned a while ago, i only had 3, turns out its 1 male and 2 females, and after around 50 eggs hatched, i now have 4 inch long bronze babies in with mums and dad in my 30 gallon, so around a 10% survival rate, but i did nothing special, i just removed the eggs and left them in a smaller barebottom tank. it was great to see them grow up, but now i cant really save any more as my tank would be over stocked, its heartbreaking when you can see them wriggling away in their eggs on the side of the tank, knowing that they are doomed the be fish food for the neons as soon as they hatch out. i am so tempted every time they spawn to swipe out all the eggs and grow them again, but i wouldnt want to part with any so its a bad idea. good luck with your babies.
