Hey there. I would recommend reading through this husbandry program if you have not already.
https://chameleonacademy.com/chameleon-husbandry-program-getting-started-with-chameleons/
Everything on that site is correct husbandry info. Another good source of correct info is Neptune the Chameleon on Youtube.
You have to be careful with the research because unfortunately there are a ton of incorrect sites out there teaching info that will kill chams.
Bring your questions here. We can help guide you. First step is learning correct husbandry. 2nd is seeing if you have a good reptile vet near by. 3rd is setting up your cage and making sure it is hitting all the correct levels. Last step is buying a chameleon from a reputable breeder. This is extremely important to be successful. Granted I purchased petco babies. However this can come with heart break if you get an unhealthy one and when you are new to the hobby knowing the signs of an unhealthy chameleon is difficult.
Keeping chams isnt necessarily hard. It is just a ton of info to learn and a lot of correct husbandry you have to implement to ensure they thrive. Knowing that a lot of chams become more like having a fish tank as some do not like human interaction is also important. They are not all friendly, while you can absolutely get a friendly one this too can change as they mature because they can have a personality shift. If you are ok with a look and dont touch animal in your home then that is great. Just would not recommend it if you are only about having one you can hold and take out. I would also recommend going with a male over a female for your first cham. Females can have reproductive issues which can be a lot for a new keeper to deal with. Their husbandry is very similar but they have more specific needs around basking temps and feeding amounts to help control their clutch sizes. Females will lay eggs even if they are not mated so they also require a permanent lay bin in their cage.
