My pair of black convicts have been digging pits in the sand for the last two days, but they haven't laid any eggs yet. So far there are four holes in the sand all about 2-3 inches deep and 4-5 inches in diameter. I know that the holes are being made by the cons because I have seen them digging them, but there has been no sign of egg-laying. Any idea as to if my convicts are planning a spawn soon?

I just put a clay pot in their tank as it seems like the reason they are digging so many holes is that they can't find a suitable breeding area.
no pot or slate I never saw the eggs
.. How long before they start free swiming and how long do you wait before feeding to your other fish? I have a Oscar
