Safe way to tell water dragons from one another? + pics

[raycarpetpython]

Hi everyone,

It's been a very long time since I have posted on aps, and first time poster in lizards. Anyway, I have four juvenile EWD's and I was wondering if anyone has had some success with safe ways of telling their dragons apart. E.g. Marking, some sort of tag, etc.
it is no big problem at this stage anyway, I was just curious.

Anyway here is some pictures of their setup

Get to know your lizards individual traits - they will all be different and identifiable.

IMO they should not be set up in a water environment but rather a land environment with access to water. Have you seen them in the wild? Most of their time is spent on land and they retreat to water if threatened, etc.
