there growth rate is 4 to 14 inches a year, depending on sex, temp, environment, etc, less then a pbass, so far from what ive researched they dont really need that much until they get larger, the only thing i havent quite found info on is what temp is best for the water and what temp is best for the enclosure, from what ive read they like cooler conditions, but i havent found much on it, i could also use a few suggestions on best lighting
