I would caution you to ask a few questions before buying him.
The reason I say this, is that back before Xmas I saw an unbelievably stunning betta (vanilla icecream colour, with a neon blue edge to his fins) in my local fish store.
He was flaring constantly, and looked stressed.
I wanted him soooo much.
The sales asst was happy to talk about him.
Turned out he was the only one in the whole delivery who hadn’t settled. He flared constantly and didn’t eat.
He wasn’t on sale and wouldn’t be, until he had eaten and calmed down.
I went back a few days later (I REALLY wanted him), to be told ‘he hadn’t made it’.
So I’m just suggesting that you weigh things carefully. He may settle nicely in your tank, away from the stresses of the fish store. Or alternatively, the constant flaring may be a symptom of behavioural issues or illness.
