Most fish need plenty of space to swim around. The larger the fish (and the more fish), the larger the tank you’ll need. Research the tank size requirements for any aquatic creatures that you’re thinking about getting.

Consider recreating a specific aquatic ecosystem. Read about which fish to put together in a tank. You don’t want your creatures to fight, eat each other, or compete for resources!

On a more regular scale, you’ll need to commit to regular cage cleaning and bird grooming. Cages need to be cleaned weekly, and birds should be misted every few days. They also need at least several hours a day of interaction with a human. A lone bird can get bored easily. It can develop bad habits of over-grooming and over-eating which can be life-threatening if left untreated. Toys and appropriate avian companions can help mitigate this issue, but they still require interaction with the family.

Make sure that you’re able to cater to the dietary needs of your reptile. Most reptiles are carnivores or omnivores, and will need to eat other animals like mice, crickets, rabbits, and birds.

Some reptiles can live for up to 40 years – or even as much as 100 years. Make sure that you have enough space. Snakes and some lizards can grow to very large sizes (over ten feet long), whilst others stay very small (under one foot long), so once again it is important to decide what type you want before you set up an enclosure.
