Been doing some research about more aquatic species. For now ruling out anacondas. So looking at 3 species.
1. Elephant Trunk snake. Main issue is cant be handled much and are almost purely aquatic only leaving the water to bask for short period of time.
2. Puff-face water snake. Semi aquatic but eats fish as primary diet. Can be bitty and most are imports.
3. Cerberus (dog face). Not much info around on them but another mildly venomous species and most likely be ruled out purely for that reason.
Please share your experience and thoughts.
