I am a reptile keeper at Omaha, NE's Henry Doorly Zoo. I have numerous exhibits I maintain, one of which houses two adult Australian Merten's water monitors. Both these lizards are housed in a large vertical tank with a large pool on the bottom. The visitors can look through the front of the exhibit and see underwater or up above, where the lizards usually hang out. There are tons of branches and driftwood pieces that the monitors bask on but the aquatic viewing area is a little sparse. I would love to plant it up but unfortunately the 2-3 feet monitors have trashed every plant I plant. I was thinking of mounting java moss or some type of moss that doesn't have a delicate root system or can really take a thrashing, any suggestions? I would also love to put small fish in the tank, however the lizards will eat any fish that are too large. I have tons of guppies in there now that are too small to be noticed. Are there any species of rainbow fish that are small? The water is drained from the bottom, run through a large Fluval filter and pumped back up so that there is a small constant water fall trickling into the exhibit. I'll try to post pictures tomorrow. Any suggestions to make this exhibit look better?
