I am not technology, so this is the only way I know how to do this.
Here is a 30 gallon tank set up for red efts (picture taked with a couple of days of construction, before all the plants grew out)
Same tank adjusted to add a large water feature (the efts are beginning to morph into adult easter spotted)
This is a 35 hex tank as originially set up. Later I raised the water level to house 3 firebelly newts (they have since been moved to another tank)
Same tank adjusted to simply terrestrial to house 3 bumblebee toads...
Finally a little 10gallon tank, original home of the bumblebee toads.
The only advise I give is: close your eyes, be the creature: in what would you like to live? Is there something to do? Is there somewhere to go?
Is there somewhere just to hang? Sleep? etc.
Enjoy the process... and remember: no matter what you will never be completely satisfied that might be the reason most of us have mutliple tank/enclosures... "I can do better next time..."
