My 8 month old GABF is getting ready to move to a new enclouser. I want to set it up to have a good sized water area as well as a land area. How would i separate the water from the substrate? I dont have a plexi glass divider readily avaliable so i was wondering if there would be another way to do it. I also would want a filter for the water area, what should i get? Any help woul be appreciated, and if you have a water/land setup some pictures would be super helpful as well!
