Tank for Crested?

[Oplr]

Im new to looking after geckos or any reptiles and have been told to look for crested as a good starter gecko, Instead of buying a new vivarium, I was wondering if I could use my aquarium? Itd be emptied of water obviously. Its 36" in length, 15" wide and 18" high? Would this suffice for one crested? Would two live in there?

u could use it as long as its turned with the long end up. crested like to climb so u need to give them more room higher not long.
