I can't remember if I saw that it was galaxy koi or just koi, that was said to change colors every few weeks/months or so. Is that true?

Ill second that!
Full marbles will change often, and drastically usually.

Koi Bettas do have the marble gene but most aren't as drastic. Not like a complete colour change such as from blue to red but more often pattern shifting or adding a new colour to the pattern. (in my experience!) For example, I had one kid that when I got him was pale yellow and white. A few months later he was a bright canary yellow with black and Hellboy pattern and blue iridescent patches.

Sure!
Some good online sources are Aquabid and eBay. Though most of the breeders on Aquabid are from overseas so if you don't want to work out transhipping and all eBay might be better.
Personally, I've gotten my koi Bettas from pet stores in my area.
So, just depends on what you're wanting to do!

All marbles, whether koi, nemo, galaxy, etc will most probably shift patterns. Some may even change colors. People are saying, marbles with large color pattern, such as nemo, are more stable (I can't confirm since I stay away from them).

Only very few have bred out the marble to make betta's colors/pattern more stable. But most haven't since it's quite difficult to do. Plus they may lose the pattern if they breed out the genes.
