Would a 13ft. x 13ft. x 40in. Indoor pond be a good size for one amazon red tail catfish, or would it need to be bigger?
 
IME, if you get a male, you might be ok for a long time, if not life, plus you could have other fish in there too.

If you get a female, it might last 5-10 years. My opinion, is all. Out of ten, I have 4 left in my 13x13x4.5. Two 2.5'-3' males and two 3.5'+ females. They are roughly 5 years old.
 
I only plan on having the one red tail in the pond no other fish and open swimming space with a couple good size hides for cover but no decorations cause the glutinous beast will try to eat them! May increase size to 15’x15’x4’

The hides are not needed for an RTC in my opinion, unless from strong lighting or predators of land and air.
 
I was also wondering about the substrate; I know gravel is a bad idea, but I can’t decide between sand or bare bottom, so I am curious what everybody’s opinion is on that?
 
All my tanks are bare bottom. Vacuuming a tank or pond that large will get pretty old pretty quickly, I'd imagine. I remember having to vacuum my 40'x6'x2.5' in our basement and shudder how much crud always hides in substrate.
 
Okay, this is the plan so far 15’Lx15’Wx4’D bare bottom pond with a couple big hides, hidden intake and output(so the stinker doesn’t get any ideas of eating either) and a huge diy sump with the heaters in the sump (figured that would the safest place). Stocking list: 1- amazon red tail catfish. How does that sound?!

Sounds good. Have you thought about placing the sump above the pond's water level and have the return as a waterfall? Keeps it out of the way and will aerate the water.
