Best advice is to read lots of caresheets, get a couple books, and look through the care of all the species that catch you eye. THEN, being honest with yourself, ask yourself if you can provide all the things that species needs. If yes, then continue researching, if no, then look for another one. And then, if you think you've found the match for you, come here and ask specific questions you may have.
They are tricky at first but they are great animals to have in the house. But it does take lots of research and devotion to keep them healthy and happy.
