The eggs are very tasty treats for most aquarium fish, so you'll need to remove them with a credit card or similar tool and put them into their own tank. The new tank must have very similar water properties as the original tank. The water properties need to very stable. You need very pure water and a neutral pH if the eggs are to hatch. You should know in about 3 days if you have little ones.
