Betta Fish: Welcome home Chihiro :)

I know I shouldn’t have bc they don’t care for them well at all but I was at petsmart to grab a couple Anubias plants with a gift card I got for Christmas and I saw this “Dumbo Halfmoon Male” and I simply couldn’t help myself from taking him home. I had a cycled 6gal cube with just some ramshorns so it was kind of fate lol. Does what they labeled him as seem correct ? Also he has some bright pinky/red on the top of his head and I rly can’t tell if it’s ammonia burn from being in the godawful cups petsmart keeps them in or if its just his coloration so I’m excited to see how he changes ! Went with Chihiro like from Studio Ghibli bc my other betta is Ponyo haha
