What would be a good size tank for my Kingsnake?

[squatsnstilettos]

What species of kingsnake?

Personally, I would go with a 3x2 or 4x2 enclosure like an Animal Plastic or similar instead of the 75 gallon. Remember, fish tanks are for fish, not reptiles

I would probably go 3x2 if it is a smaller species of kingsnake.

Good point! He's a banana snake and weighs 11grams.
