I've put one 40 gallon rubber tank in an flower bed under my deck. So far I have a Fluval 1 filter in it, a ramp in and out of the enclosed area, sun rock, plants.
I'm digging hole for another one. My one 5 inch red slider seems to like being out of the water sunning under geranims the best!
How deep should the water be for him to be happiest? Does he need a friend? Do I need Fluval 3 filters? What about an airstone? etc. Heater.
Has anyone figured out how to fence against birds etc. without hiding the great view and access to the turtles?
