Tank size for an adult (adolescent?) male

[harper]

I have a male BP, about 15 months old. He currently measures exactly three feet long, weighs 830 grams, and is housed in a long 20 gallon tank. From what I've read, it sounds like he probably doesn't need a bigger tank right now, but will before too long. And even now, I feel like there isn't enough space. He keeps knocking one of his hides into the water dish, and there's barely enough floor space outside the hides for him to move around.

So my question is, what size should he be upgraded to that will be large enough for the rest of his life? I've read anything from a 20, which is obviously going to be too small, up to a 55, which seems too large. This is my first and only snake so far, though, so I'm a bit clueless!

I would say maybe a 40 gallon breeder if you clutter it up a lot, if you really feel he wants more space.

You'd be surprised how long he'll stay very happy being kept in that 20G long.

Until it gets cramped and you can't fit appropriately sized hides at either end and a water dish in there, you really don't need to upgrade in size.

I definitely agree. He'll be happy for a good while.

A male should be able to live the rest of his life in a 20 gallon long but no bigger than a 30 gallon long!!
