Welcome to AC! I have anxiety and sitting in front of my aquariums and watching the fish is really calming. You will love it and probably end up with lots more aquariums before you know it. I started with a 10 and now I have 2 10s, a 20, a 40 and a 55. LOL
Not sure if you have it or not but you may want to get a good heater for your aquarium if you are going to have tropicals and the tank water risks dropping below 72.
I have a heater. My water usually stays between 75 and 77 degrees, and that's with my ceiling fan on high. If I turned the fan off, the water would easily go over 80. I plan to put the heater back in towards winter.
Thanks for welcoming me.
