Things to Consider in a 40 Gallon Reptile Tank
There are a few things to consider when purchasing the best 40 gallon reptile tank to ensure it is going to be comfortable for your pet and practical for you as the owner.
Type of Reptile
Reptiles come in all different shapes and sizes, so what will work for one pet might not work for another. If you’re housing a smaller snake, you might not need to worry about the length of the tank, but if you’re trying to find a tank for a ball python, then you’ll need to look for something longer. Some reptiles can be dangerous or more prone to escaping, with which you should consider a durable and secure tank that they can’t escape from.
The size of your tank is one of the most important things to consider. You don’t want your pet to be cramped! While you may take your small animal home when they are young, you should consider the size of them when they are fully grown, so you don’t have to keep buying a new tank every few months.
Capacity for Heat and UVB
Many reptiles require heat lamps and UVB light lamps to stay happy and healthy. Some tanks have this automatically built in, while with others you will need to attach your own lamps. You’ll also need to make sure your tank is big enough to accommodate the size of the tank heater.
The design of your tank goes hand in hand with the type of reptile you have. Some reptiles will want a vertical tank, while others will want a horizontal one. It is your job as their owner to recreate a suitable habitat for your pet — so, if in the wild they would be climbing trees, a vertical tank with lots of space for branches would be best. However, if your pet is a natural ground dweller, you might want a tank that is wider but not as tall.
If you are housing aquatic reptiles, such as box turtles, you’re going to need to ensure that your tank is suitable not only for the right amount of water, but also for keeping the water clean. This means making sure there is space for a water pump and filter, and ensuring there is adequate ventilation so the water doesn’t go stale too easily.
Once you have set your reptile cage up, you’re probably not going to want to move it around. However, there may be some occasions when having a portable or collapsible tank is useful, so this is something to think about.
Now you know what to look for in your reptile tank, take a look at the best reptile tank starter kits we’ve picked out below. These 40 gallon terrariums are all available to you on Amazon.
