Dumeril Tank Size

So Im thinking about getting a dumerils from my local reptile store and Im curious about the right tank size for him.

He's about 3ft long and has a diameter of 2ish inches.

What do you think? Will a 20L work? or would a 32Qt sterilite be better?

A 20L should be ok for awhile.. I think tubs are better for snakes in general. one of the 3' long tubs would be great for your little bugger.

Just remember they can get rather large!!

Yes an adult is going to need a 4' cage ultimately.

I know I'm in the process of building a few large cages. But I was curious if I could use what I have. Before the cages are built

Sure you can. Dums are pretty easy to keep happy.. adults anyway.

i think a 20 gallon tan is fine
