[It's definitely something Akko would try to show off in earnest if Sora asked, but... There is really no guarantee of the results coming out well. Certainly not a swell as his butterflies just now. He's probably better off learning it for himself or asking her some other time when she's got a better handle on it.]

Flying fish? [She laughs.] That'd be a good choice if this place celebrated Children's Day. You'd kill it with some flying carp!

[She shakes her head a little.]

Butterflies are a good place to start. They're small, so probably a lot easier to concentrate on keeping. And they're always pretty. I mean, have you ever seen an ugly butterfly?

[By that logic, Akko means to imply it's practically impossible to fail. Whether one is going for form or function, they have to be able to accomplish one of them decently.]
