I would guess male. Or possibly female. Haha! I'm terrible at that stuff. I can tell once the fish are about 12 inches long, based on their body style, but small fish are impossible.
Just wanted to say WELCOME to the GPF! Do you have a pond?
Hi, I read that females have rounded fins and males have pointy fins, but even if it is true, fins on a young fish can change as the the fish grows so....
All my females grew large at a faster speed, but until I witnessed the behavior during mating season (male chases female), I really didn't know for sure, and for this to happen the fish has to be at least a few yrs old

I agree with @Jhn , koi can handle extreme temperature swings, in adequate depth and water volume, so if you have the room, an outdoor pond would be better for your koi than an indoor tank IMHOWelcome.....Koi can handle the temp swings from being outside year round. Also there are many ways to keep predatory animals away from your koi. Easiest way is to place a net or screen over the pond. If you want to do a pond there are plenty of us here to help with design and advice to help you be successful.

....as you can see in my avatar I covered my pond to protect my fish from the many predators I share my land with, so predators shouldn't be what's stopping you from building an outdoor pond
