Anaconda water issue

[MyNameIsJordan]

Hello everyone,

I bought an Eunectes Murinus (green anaconda) a few days ago at a reptile fair. It’s a 2 months old female and I could use some advice on the watering. This species loves water and mine spends her entire day in the water, but the water turns cold really soon so I wanted to know how to fix that issue. I have a regular water bowl where she fits in entirely and can stay underwater. What temperature would you recommend to keep the water at and how can I best achieve this imput. I have both heat lamps and heat mats available. I can’t upload photo’s from my phone due to the size being too big...
