Thanks for all of the recommendations!
We had a family party and relatives came over and I asked them about owning a fish. Surprisingly, my uncle use to have fishes when he was younger and knew a lot about them. He brought me to petsmart and got me everything I needed.
I now have a 5 gallon tank as a starter and a small blue and black betta fish named Xshiphin (ex-shi-fin).
Everything is going well, nothing wrong with anything. I also have a few questions, Do fish sleep? I mean, should I keep the light on 24/7 or partially?
