The 2 angel fish in my 90 gallon have spawned. I came home tonight to find them aggressively guarding a clutch of eggs. Not sure how many but I'd say there is at least 100. What in the world should I do? The eggs were laid on a rock. Should I remove the rock and place it in a 10 gallon tank? Should I leave it alone and let nature take it's course? If the fry hatch what should I feed them? Any help would be appreciated. It was a totally unexpected find.
