I used a fluval 1 in mine(when I had such).Using a piece of plexi to section off an area for water(neons,firebelly toads,etc)I then used a layer of small gravel,layer of charcoal,then good potting soil(no styrofaom bits),this helped with any exsess water draining.The plants you use are up to you(personal pref).Just pick up a plant light for the top and and your critters and presto!!
