ya i ment the 20 long tall, but im getting a beautiful dalmatian crested gecko sent to me in a few days but he/she is still small so i have to have he/she in a 5g 10g i have, but meanwhile while time passes im going to work on the converted 20gal that i have been working on. So i already have cocofiber and am now thinking of getting some sphagnum peat moss since you are able to grow just fine with it, but is this all i really need to be growing plants in (besides the lights and water) i also have this extra 30-40 gal filter im not using and was hoping to either incorporated it into the convertaded 20 gal somehow and have some small aquatic thing or either make a simple water fall work, but im not sure if that would be going to far and if that would even work out with the geckos i am planning on breeding in the 20g. but since you are so far on yours and plus you also have a crested gecko i wanted to know if you had any suggestions on what im doing, and if the water thing would even be safe with the little guys?wait witch one there both 20 gallons (lol), my 20 long tall crested gecko has a mixture f coco fiber and sphagnum peat moss don't really clean it out and mostly use the gecko poop as fertilizer. the viv im building now (20 tall tall) has some stuff called fir & sphagnum peat moss mix by Zilla and i actually really like it going to see how it grows plan though.
