There is only one person who can answer this question, and that is of course yourself.
Tarantulas are generally suitable animals for observation. So if you are satisfied with observing them, you will be happy with keeping tarantulas as pets. However, if you expect an active interaction, let alone social interaction with you from your pet, a tarantula is not the right choice for you.
Like any other domesticated animal, a tarantula requires a certain level of care and therefore your time. However, compared to other pets, this care is completely minimalistic, and for keeping one tarantula, it can be quantified in minutes per month. Nevertheless, it is necessary to take this into account, as the minimal time required compensates for the duration of care that you will have to provide for your tarantula. The achievable lifespan of tarantulas varies from species to species, but for example, female Brachypelma can live up to 30 years.
It is also important to consider the impact of keeping a tarantula on other members of the household. It’s great that you have decided to keep this amazing animal, but not everyone sees spiders the same way. If there is someone in your family who is particularly averse to spiders, consider whether you want to expose them to the presence of an exceptionally large spider.
To sum up this introduction, gather as much information as possible about tarantulas and then make your decision. If you do it the other way around, there is always a risk that you will regret your decision.
