So my angelfish that bred took care of the eggs until they became wigglers but they started to eat them. Seems the wigglers wouldn't stick back to the surface, so they just ate them. I have removed the parents from the tank but now the fry are just falling to the bottom of the tank. Will they survive on the bottom until they are free swimming? The tank is bare on the bottom. If not then I guess I will have more chances in the future to get this perfected.
