Hi, I have had just two Oscars from babies, and I consider myself extremely lucky, because 1 month ago they bred, unfortunately all the eggs were eaten, but last thursday they laid again, this time my son rescued them and put them in a tank on their own, a lot were destroyed by fungus, but today about 1-2 dozen hatched, I thought that it would take another 3-4 days before they fell off the slate, but they are all hopping about the substrate in the tank, can anyone tell me how long it takes for them to grow to 1 1/2 inches
