A couple of questions if I were to pull the eggs on a future spawning. I have both a sponge filter (not yet seeded) and air stone. Are both needed at the time the eggs are first removed to the new tank? Or just the air stone until there are free swimming fry, then I add the sponge filter?

If I were to use hydrogen peroxide instead of methylene blue, how much would be needed for about 3 gallons? And am I correct that this would have to be added each day (but methylene blue only once) until there are wrigglers?

How long should the sponge filter be in the main tank to be considered "seeded"?

Thanks for any assistance.
