A few times a week is moderate to me, but it depends on who you ask. Personally I only bring mine out if their tubs/vivs need to be cleaned and for photo shoots and at most that's 10 minutes per snake if even that.
I'd look into dwarf boa males, but note that snakes have individual personalities. A few of my boas have no issue hanging out but a few are pretty squirrely and don't like to sit still.
Hog Island boas are spelled with only one "g"![]()
My Hog girl is actually pretty active out of the tub and doesn't quite like to be held as much as my other boas but it depends on the snake. More handling should calm down *most* snakes.
