Angelfish breeding advice
Two of my angelfish paired off and laid eggs on the filter intake tube (don't know why, I have plenty of swords and slate pieces). Anyways, they were impossible to guard and were promptly devoured by my other tank inhabitants. I'd actually like to keep the next batch, though.
How often do angelfish lay eggs?
Should the parents stay with the eggs?
Is there any object I could put into the tank that they would be encouraged to lay eggs on?
