Where did you read that? Cant say I have ever heard of butterflies requiring natural live foods, and I have personally kept butterflies with success without. You should have no problems with some of the smaller, hardier butterflies in a 45g tank as long as its mature, atleast 6 months old. Some suitable butterflies would be: punctato, lemon, auriga, and heniochus bannerfish. All of these do fine on standard frozen foods like enriched brine, mysis, formula 1 and 2, etc.
