wow you would think it would have HITH or something being 14" in a 75g holy..... ya i honestly dont know genetics of the two oscar i have all though one is a rescue i got form a girl that was keeping it in a 30gal tank and she is prolly 10" and figured she hit a growth spurt since being in a 30g her whole life and now in my 130g 6ft'r but nope hasnt grown a darn bit, and my tiger oscar he is 7" or so and i got him this past spring or so maybe march or april ? he was like 2 inchs at the time so tiny hehe honestly i would absolutly LOVE a peacock bass in my tank, but have been told they will be to large to keep in my 72x19x24 tank
