Sometimes I see requests online of people looking for aquatic turtles or large tortoises. My response is always the same.
Aquatic turtles are one of the hardest non-giant reptiles to manage the care of, because their water needs are great, and they are pooping *machines*. A general rule of thumb is 10 gallons per inch of shell, and to have a filter system rated for several times the capacity of system. This means that a red ear slider, that starts life as a 1inch little buddy, will require at LEAST 100gallons (the classic 2x2x4), proper heating and lighting, and a pump and filter system for at least a 300 gallon system, and you're probably still going to be doing a LOT of maintenance to keep that clean.
Smaller tortoises like a Russian Tortoise are generally much more attainable to give a good setup for... But they also get into a humans retirement age with relative frequency! And when you get things bigger like a sulcata they live as long or longer, but also become 3ft 150lb boulders who have no concept of a fence.. or toilets like the photo here shows. I've seen with alarming regularity massive tortoises lost or found because that 150lb boulder does not care what you think it's enclosure looks like. If it wants to try the neighbors grass you're going to struggle to contain them.
It's so tempting to get a small reptile and have a small setup, but a small setup is not going to last. You will be sinking tons of money into getting them an adequate setup. Many don't seem to understand that. And since animals should be a lifelong commitment (barring absolute emergencies, not here to yell at someone for suddenly falling ill or anything) you need to be prepared for tort-hulk to smash. And honestly this is all surface level.
So many of these animals are impulsively gotten when they are small and cute, and rescues get slammed with requests to take them in, which is hard to do alone, let alone when you've got multiple animals you're already taking care of. They require a ton of space and resources that rescues are always tight on.
If you're dead set on getting one, prepare for them at their biggest and strongest, and consider adopting. These guys are generally very long lived critters and it's not unheard of for someone purchasing them in their late 20s and early 30s being outlived by their animals by a decade or more.
