Thanks everyone!

Can the double mini deep dome light just sit on top of the ExoTerra screen on my 18X18?

What is the best to use for cleaning the inside of a tank, what cleaner should I get I imagine there
is something special from PetSmart or something


If I am going out of town two days should I leave two crickets in the tank or not feed for two days?
A last minute family emergency came up and I have no other option.
