I've come to really like this tank, rock and plant choice.
I think adding the mantis is cool too.
Feed the poor beast!!!
Take a good pic and see if you can fool folks into thinking it has water, till.............they see the mantis.
Next, get some water scorpions.
They would look similar, but be aquatic.
They last maybe 6 months in tanks.
