Enclosure Size Question

Hey guys! I’ve got an adult male (ETA; Kenyan) sand boa who’s going to be 6 years old in a few days, he’s approximately 19” and 130 grams.

I don’t like the enclosure he’s in right now. It’s a 36”x18”x12” front-open PVC enclosure. It’s working fine for temperature and humidity gradients, and his clutter all fits, but it being so short makes it a pain in the ass to get in there and do anything.

I’m considering ordering a 36”x18”x18” for him when it comes back in stock, and then siliconing it ofc. Same floor space, but big enough for me to more comfortably get in there, and a taller substrate screen in the front.

But I also have an empty glass 75 gallon tank. It’s I think 48”x18”x24”, which is way too tall and will make it more difficult to heat. I’ll need to cover 3 of the sides and possibly insulate it. **And clutter the hell out of it.** I’m aware of all that, I’m willing to throw time, elbow grease, and money into his next enclosure so that it can be his last enclosure. I know which hides he prefers. He’s active at night. But during the day I have no problems finding him in his current enclosure.

My only concern is the 75 being too big. I know that “as long as you have enough clutter, it’s hard to go too big”. A 19” snake in a 48” tank seems a little like overkill though. But it also sounds like a **palace** if I set it up *correctly*.

So I’m looking for some advice from other sand boa owners. Do you think the 75 is overkill and I should hold onto it for something else in the future? (It *is* good storage right now for extra reptile supplies, I’ve got 4.) Or should I just get him the 36”x18”x18” enclosure when it comes back in stock?
