The best way to start your aquarium journey is to find the best aquarium store in your area and to find out what tank fits what you want. In terms of tanks, I would go with the Fluval Flex 9 gallon. I have multiple of these tanks and they come with a filter (foam and bio media) to put in the back compartment and a pump. In terms of getting all the other supplies, you can look up "best aquarium stores near me," then call your local fish store and ask if they have aquarium grade gravel/sand (up to you), rocks/wood (up to you), and aquatic epiphytes (plants that don't need to be planted into the ground and can be tied on decor), and string (fishing line works great). Choose between gravel vs. sand, wood vs. rock, and what epiphytes (plants) you want. I would highly recommend getting gravel, rocks, and anubias or java fern (plants that you can get in my storefront). Once you obtain these iteams, rinse the gravel and rocks in a bucket, position your wood to your liking, and plant your plants.  If you don’t feel like finding a fish store in your area, there are links below to where you can buy the highest quality products for fair prices online (you might get better deals in your local shop, but it depends).

In my eight years of experience, the mistake I see too many people make is not to cycle their aquarium. You must cycle your aquarium because it is crucial to establish beneficial bacteria that breaks down toxic ammonia and nitrites from fish waste into less harmful nitrates, creating a stable and healthy environment. Without proper cycling, fish can suffer from stress, poisoning, and even death due to poor water quality. Once you set up your aquarium (after you put in decor, substrate, plants, and water), put in a cap full of the Aquarium Quick Start (in a 9-10 gallon tank) and leave the tank alone for 2 weeks before adding fish. I know it seems unnecessary, but in reality I have made this mistake and it ruins your tank with algae and has the possibility to kill your fish, so wait the 2 weeks then slowly introduce fish (I would start with snails, then gradually keep adding other aquatic creatures). 

Tap water conditioner is NOT OPTIONAL, unless you don’t have a full house water filtration system that is saltless. Water conditioners remove toxic chemicals (chlorine and chloramine), heavy metals (lead, mercury, zinc), organic compounds/organic gasses, and debris that otherwise would be very harmful to fish. Also, it increases water clarity because it removes debris. Overall, unless you possess a full house water filtration system, it is vital to purchase tap water conditioner.
