ID sharks triple in size in half a year, but channal catfish double in size i half a year
This has been my experience with ID's. Mine is growing like a weed. (I don't have a channal cat though.) At first the ID wasn't growing super fast, but sorta grows in spurts, and is currently going through a bit one right now. I was just looking at him tonight and realizing how much bigger he is. He was probably 7-8" when I got him in March, and 5 months later he's about 14+" and almost growing on a daily basis. He's fed the variety that I throw in my tank: massivore, sinking cichild gold pellets, algae waffers, steamed tilapia and shrimp, and krill. He seems to be developing nicely on this mix, and has been extremely healthy.
They are very much a schooling fish. I feel bad that he doesn't have a couple others to hang out with, but he was rescued from a 40 gallon tank. Eventually, he'll get some friends, but till then he has adopted the tin foils as buddies (although I'm not sure the tin foils are all that thrilled about him). I'm sure if he had a conspecific in with him, he'd be thrilled.
They can get up to 52", but its not just the size that makes them a challenge to keep. From what I've been told, these guys remain active swimmers through out their lives. So, figure that if you do it right, you'll have a group of very large fish who some say have a tendency to spook. Mine is fairly relaxed but he does flinch if something knocks against the tank. I guess a 52" fish 'flinching' in a tank would not be such a good thing.

I saw that you are working on a pond, so that's good. If the pond is completed by the spring, he'll probably be just fine in the 150, but its gonna start to get tight in there. Mine is starting to look big in my 180.
GL. Updates please.
