I'm new to this site and would like some help in planning out my viv for when I get home from my deployment in Iraq. I've actually been keeping all kinds of terrariums for since I was 12. I know that a lot of you have suggested not to mix species, but I've found that in a 55 gallon terrarium 3 Anoles, 1 Brown Anole, 2 House Geckos, 1 Green Tree Frog, 1 Cuban Tree Frog, and 2 Firebelly Toads can do alright. Anyways, I plan on getting either a 150 gallon or 210 gallon aquarium when I come home. I plan on making an area either 18 inches long and 18 inches wide, or 18" L and 24" W as a water area. I want to make a waterfall and some step areas in the water portion. I like the pics that people had w/ the GS, but feel kind of nervous about using it. I plan on using a fluval style pump for the waterfall as opposed to an internal one. I love using real plants in my terrariums, especially Crotons and Ficus Elasticas. My main question is can the GS be used underwater? Can anyone also give me some ideas for live plants besides the small offerings that you can find in Lowes or Home Depot. As a side note for whatever reason every terrarium I have, I end up having my "critters" breed. I really enjoyed my terrarium I had before my deployment (It had to be taken down because my wife thought it took too long to take care of.), anyways I got 2 Brown Anoles, 1 Green Anole, a Chubby Frog, 2 Firebelly Toads, and a House Gecko for my 55 Gal Terrarium. Next thing I know I've got 5 more Brown Anoles, and a Tadpole. I really enjoyed watching all of these go from a hatchling to Adult size, and then the Tadpole to a small Tree Frog. My very aggressive Brown Anole who I called Godzilla ended up eating the Froglet I think, and then one of the baby Brown Anoles. Anyways any help would be greatly appreciated. Thanks.
