Ok so I have had my Oscar for about 1.5 years now and it's only about 8.5 inches. Is it because its female? Poor genetics? Just a slow grower? It gets plenty of food and the tank has great water quality.
Oh ok it was just a thought. It's probably like you said genetics.
Sorry everyone but one more side question does this sound like a normal growth rate for a JD I have heard they grow slow. It's grown from 2 to 4 inches in 2.5 or 3 months.
