ive raised these fish for many years in the past. theyre starting at 1 inch. i will upsize the growout tank when the time comes and then will add them to the monster tank next year. i fully understand the proper care and growth rate of these fish.I don't think you understand how fast these fish grow. I would focus on something better for that size tank. When you can get a bigger tank then get them. They will grow fast and will be big before you know it.
Keeping big fish in small tanks is cruel IMO.
