Why is my red tail not growing very long unlike the shovelnose but it is turning fatter with his bigger head than the paroon?

Redtail Catfish grow in length relatively fast until they reach about 15-20 inches, I believe. They usually slow down growing in length, but they will still grow in girth. All you need is to be patient. Full grown RTC's can grow 5-6 feet long. Pretty soon you'll need a bigger pond for that beast.
