Oscar fish You may find that if you oscars lay eggs they may not do it again for a few months it may be the first and Oscar fish eggs hatching nowadays the aquarium and may develop many ways to be able to talk to. Then the omnipotent powers of the time for your oscar fish. I have had oscar fish for 3 years now and my oscars started to mate and my female oscar is most definitely going to lay eggs. As far as i know it takes the eggs 24-36 hours to hatch. About 72 hours after they were laid there s lots of activity and i think they are about to hatch. As for the hatching time it mainly depends on the temperature in the aquarium or pond.
Generally it would take from a couple of days to a week. If the water is hot or you heat it once the eggs are fertilized they may hatch in less than three days. On the contrary if the temperature is low and cold it could take up to a week and more. In the wild spawned oscar eggs often have a lower level of success rate and even fewer make it to young adults. In captivity hatching rates and conversion rates can be much higher. Take this into account when deciding on rearing tanks. The oscar fry will hatch from the eggs within 72 hours of being laid.
My oscar fish have laid loads of eggs. They have eaten some as i take it they are the bad eggs. Has anyone had oscar fish that have actually successfully had the eggs hatch and is there anything i can do that will help I mean i dont want to start interfearing with nature but does the temperature need to be altered or anything like that
