What animals can comfortably live in a 120x60x60 cm terrarium (approximately 150 gallons)?

So here’s the deal—about four years ago, I bought a 120x60x60 cm terrarium during a sale. The plan was to get a ball python, which kind of happened because my then-partner and I got a baby ball python together. However, things didn’t work out, and he ended up keeping the snake. So, for all this time, I’ve had this empty tank sitting around.

Now, up until now, getting a new pet wasn’t really an option because my sister has a phobia of anything involving dead mice or insects (pretty limiting for reptile care). BUT she’s moving out! Which means I finally have the freedom to bring home any animal I can properly care for that fits comfortably in the tank!

I’m planning on setting up the tank as semi-bioactive, meaning I’ll add some plants and isopods to create a self-sustaining environment before introducing any animal. The tank will be in a sunny spot, great for plant growth. I already have a heating pad that can warm up about half of the tank, providing a warm and cool hide, and I’ve got a humidity reader too.

Years ago, I was all about snakes and even had a few months of experience with that ball python, but now I’m more open to different kinds of pets. Back in the day, I also researched blue tongue skinks, and I loved their diet variety and the fact that they kind of look like zucchinis with legs!

Here’s the catch: I’d like to avoid animals that need crickets or roaches in their diet, as they freak me out too (just like my sister). But I’m totally fine with slugs, worms, and any type of insect that doesn’t hop or crawl around unpredictably.

So, what animal should I start obsessing over and studying the care of? I’m open to snakes, lizards, geckos, amphibians, etc. I’m still kind of a beginner, though, so I’d prefer to avoid species that might be too advanced for me. I want to make sure I’m fully ready to give my future pet the best care possible.

and sorry if my English is a bit off—it’s not my first language!

A blue tongued skink, bearded dragon, probably any small lizard, corn snake, rainbow boa, ball python and basically any snake that’s under 6 ft long are good for that size of tank. a king snake, milk snake, hognose, gopher snake, African house snake, Rosy boa, Anthill Pygmy python, racer, etc are also good.

My brother has a hognose snake named Henry and he’s super cute. My brothers friends had some frogs as pets and he said they’re very difficult to take care of. I also had a blue tailed/five lined skink for a while and they’re super fun.

I don’t know what their diets are but you could probably do any bug that has protein or whatever they need, I don’t think it necessarily has to be crickets and roaches.

I’ve had a bearded dragon for a couple of years now, and I can confirm they’re fantastic pets if you want something interactive. They do need a UVB light and some careful attention to their diet (greens, veggies, and protein), but they’re super friendly and easy to handle. They’ll definitely make good use of that space!

I second the blue-tongued skink suggestion! Mine is a bit of a grumpy old man, but he’s got so much personality, and they’re pretty hardy animals. Just make sure you’re prepared to deal with their shedding and the occasional mess. They can be a bit stubborn with their food, but as long as you’re okay with feeding them snails, worms, and a good variety of fruits and veggies, you’ll be fine.

If you’re considering snakes, I’d recommend the corn snake. They’re beginner-friendly, and as long as you provide the right enclosure setup, they’re pretty low maintenance. Plus, they come in so many color morphs, so you can find one that really catches your eye! Just keep in mind they’re escape artists, so secure that tank lid!

Don’t forget about leopard geckos! They’re small, easy to care for, and don’t require crazy humidity levels. Plus, they have the cutest little faces. You won’t need to worry about crickets or roaches either—you can feed them mealworms or waxworms instead. They don’t need a huge amount of space, so you could really deck out your terrarium with lots of hides and climbing options.
