You can have the best foods available and biggest tank for them but I can
assure you that its not the reason that'll make your O big. Yes its a healthy diet
and comfortable living but the "genetic" strains in all oscars differ a little bit.
Most O's will grow huge 14"+ and I've seen a couple which only get to a 10".
Quality diet, prestine water, & tank space is pure spoiling, Lol. Chances of you
having a runt is very slim anyway. Any pics??
I have a Red Tiger Oscar that is 13", and he was only 10" when I got him so they grow, and whatever food you throw in there they eat, complete pigs when it comes to food you know? LOL
