I'll either be emptying a 20 tall or a 15 tall for it. My loach trainees are getting an upgrade, so the Gecko might get the 37. That would be a great enclosure, it's tall and I could provide a lot of foliage and branches.
Since the Vikings game sucked so hard, I went to Home Depot and got some plants, and collected some dried driftwood from the river. Let me know what you think.
