I just got a 20 gallon long yesterday, and it was planned on being used for my vertical vivarium project. Well, plans have changed a bit, so I am going to be using this for a fish tank, who can resist? I was given an opinion, which was to use my 10 gallon for the vivarium instead because there are no plans on keeping a live animal in the setup, so why not make use of the size and go with the fish tank. I planned on using the 20, only because I like bigger tanks. I am using the 10 because I can do smaller plants in the tank, and it's less of a giant project, leading to fewer things needing to be purchased for the actual build. @aussieJJDude was able to explain this to me, so I went with this idea. Anyways, I would like to upgrade my 10 gallon, and replace it with this tank! My female betta will love the extra room, considering that she is a plakat, and extremely active. I will post an updated photo in a little bit!
