What should I put in it?
(Honorary Mention: Nico, my apparent catfish) What should put in here? I’m pretty new to the hobby and only have a betta fish, three shrimp and a mystery snail. Those are my first btw. I think the tank might be a 15 or 20? My sister bought it when they caught a mouse at their house and her fiancé stupidly decided to keep it until it passed away🙁. So I got the tank. Should i upgrade my Placket Betta or something new? I was thinking maybe something that is in a group so my cats could watch them?
Edit: I found out it is approximately 18 gallons (17.964 gal) done by measuring tape🤷🏼♀️ it was 45 x 40 x 41 so google said about 68 Liters
