If I read the opening post right, the wild betta in question is Betta pi right?
Anyways, I'm not that knowledgeable of that particular speacies but I could give some tips on wilds in general.
Wild betta species do not necessarily thrive in water that the relatively common betta splendens thrive in. Some wild species would need acidic water, some hard water. Some species need some current in their tank and some would need special tank setups to make them feel more comfortable (i.e. some species would love to have some dead leaves as substrate).
So, in a word, when dealing with wild bettas, it may be best to research again as if starting again in the hobby. Research on the particular requirements of the wild species that you are currently handling would be beneficial for both you and your new fish.
