i dont get the tap water thing, used it for years and never had a problem with it, even had a fully aquatic frog it in for years with no problem. `10 gal is what i have available atm. its either that or the 55 gal which i dont have space for...i do have a small exo terra, my large one is housing my rat snake.. they are not babies they are a good size...i havent gotten a chance to get pics yet but i will soon. lobsters are what i have and im not changing it..i got mine at the columbia repticon and they looked good to me.,
