Have a pair in at least a 75 gallon tank. Up the temp to about 80-85 feed 3 times a day and do weekly water changes.
incorrect, 55 gallons is the BARE MINIMUM per oscar, so 2 would need 110 and for breeding id go with nothing less then 125 or so, sexing oscars is extremely tough and ive heard the head thing too, so far its proved true, me and my buddy bred our oscars and we have some half lution and half tiger oscars. once they pair up its pretty easy, they just go do their thing and once the fry are hatched they have a tendancy to eat a few but with more broods come more parental experience and they will eat less and less with each brood.
