will gekos survive in a big ol fish tank? (without the water)
to be honest, i found that it is much easier to retain heat inside of a terrarium specifically rather than an aquarium. Its a bit of a personal choice i suppose. Aquariums have the advantage of being MUCH larger, i know i have seen like 72 gallons + aquariums. However, i currently have a 40 gallon terrarium and only need a 75watt bulb to retain the heat. up to you, for heat conservation go terrarium, for size and room to play with choose the aquarium.
