How do I breed Tiger Oscars 1] To breed Oscars, I need to be able to tell the difference between Male and Female fish. 2]How many "pairs" per tank? 3]How big should the tank be? 4]What would promote spawning? 5]What temperature and condition should the water be? dekramitz 2009-01-10 http://forum.aqua-fish.net/?topic=how-to-breed-tiger-oscars-#2 1, Impossible to sex Oscars unless they are spawning 2,1 pair per tank 3, 1 pair needs a 100 gallon tank 4, cooler water changes, reduce the water level and increase it over a few days to replicate a rainy season. The water quality needs to be perfect mickey 2009-08-28 http://forum.aqua-fish.net/?topic=how-to-breed-tiger-oscars-#3 I would suggest starting out with 6-10 juvenile oscars and letting a pair develop from that set. You cannot sex them without venting them so the best way is to observe the behavior of a group of them. You can trade in the other oscar fish or give them to other aquarists. Mickey is correct that a pair will require around 100 gallons. My pair actually reside in a 90 gallon but it doesn't leave much room for decorating.
