What do I need for a snake tank? and is this a good tank?

[EasternGirl]

Not good for garters....they need a lot of ground space as opposed to height in an enclosure...those kind of terrariums are more for climbing or arboreal reptiles.

What's a good length limit then.

[EasternGirl]

Many people go with 20 gallon long tanks which are actually about 30 inches in length. Some people opt for 30 gallon tanks or even longer. I wouldn't say there is necessarily a limit....but for one or two snakes, many people use tanks that measure somewhere between 30-40 inches in length I would say. In terms of height, I wouldn't go with anything higher than a standard aquarium tank.
