Sounds good, you could add an aquarium filter and use an aquarium in the Viv so you can see him underwater

Maybe get it drilled and fit a drain plug for maintenance
Along the same lines but without the viewing opportunity a tank would provide, you can get rain barrels or half barrel “ponds” that are already fitted with a drain plug that attaches to a garden hose. It should be easy enough to cutdown to the depth you want.
Update on the anaconda! He’s been doing great. Did a full tub scrub down today and got him out for some handling and pictures. Also snagged his weight- 249g, up just short of a hundred grams since last weigh in. The feeders that came in for him were a tad on the large size for him, so he’s been eating every other week and he seems to be thriving on it. He’s also been an awesome handler, he’s yet to strike at me ever, and isn’t super flighty when he’s out; rather he clings on pretty damn tight and just hangs out. I think relative to size his grip seems to be the strongest by far. Here’s a photo dump! He’s starting to look slightly darker than usual, he may be coming up on a shed in the next couple of weeks.
