Betta Fish: I low key really want him

Saw this guy at the store, and I want him so badly now. I do have a cycled ten gallon (recently empty as I just put my old girl down a couple days back).
He only has one dumbo ear fin and the other is normal, it’s so cute and I’m so in love with it. He’s just not really the colour I wanted to go for next, so Im undecided if I should go back and get him (plus he’s $26 CAD, and I usually like to get discounted or free sick ones). Anyhow I Just wanted to share his uniqueness with you guys cause I’ve never seen a beta like this, and see if any of you have seen this before.
