I have an albino oscar and a red oscar. I've had them for like 5 months. I only have them in a 29 gal tank. I'm am getting them a 70 gallon tank on the weekend. They have been cleaning a hole in the rocks in the middle down to the glass for the last couple of days. And swimming around weird. Is it possible for them to be breeding in this small of a tank? If it is do i need i flat piece of slate for them to lay their eggs on, and what do i do when the eggs hatch? Please help me. Thank you.
