Looking to setup a 60 cube as a dedicated snow flake eel tank. I know they need rock work but I am at a loss of how to setup the rock work? Do i stack the rocks close? Do I open the rocks up a bit so water can flow in between the rocks to remove detritus. I threw some rocks into the tank to start cycling but not sure what to do. Do I need to make PVC homes between the rocks?
