As stated in a previous post, do not put your needs (the desire to see it more clearly) above the needs of the animal (the need to feel secure, the need for appropriate temps, and the need for appropriate humidity). A rubbermaid tub can provide all of these needs. An aquarium will not provide any of them. You indicated that others have mentioned using tubs with this species yet you are still considering using an aquarium.
Buy Greg's book and read it. It will discuss why tubs make for appropriate housing. It also has a very interesting section regarding people who ask for advice on the care of these animals then ignore it and do there own thing, only at the expense of their animal's health.
There are people here on this forum, as well as other forums, who are sincerely interested in helping you, and others, have a positive experience keeping these animals. The trick is to be willing to take the advice of others and assume, if you are getting the same advice from several keepers, you should follow it. This is your opportunity to learn from other's past mistakes so you don't have to make them again.
Good luck,
Bart
