Is it in a place with a lot of temp fluctuations (e.g. by an exterior door, or by a vent?)
-Where are you going to put the tank? Is it outside? Is it going to get a lot of sunlight? Is it in a place with a lot of temp fluctuations (e.g. by an exterior door, or by a vent?) How much activity/traffic is going on around where you want to put it? Will other pets and kids have access to it? Is there an outlet by the place you've picked out? How much work will it be to do water changes (i.e. how close is your tank to a water source)?
