5 years ago, I was told at the petsore goldfish need 10 gallons, so I bought a 20L thinking I was doing my pet a favor.
(Please ignore the SUPER sloppy tank background-- I need to buy new mirror paper.)
Does he look too big for this tank now? I'm terrified of getting a bigger tank because I'm moving to another apartment soon, and I'm afraid potential landlords will imagine 40+ gallons of water gushing over my floor and through the ceiling of units below. But I've grown very attached to this guy, and I really don't want to have to say goodbye to him.
What's the minimum size I could get? And has he even stopped growing? He's about 5 years old. I was considering a 55 gallon so I could play it safe and never buy another tank again, but I've heard the filters are deafening and the tank would likely be in my bedroom.
Any help/ input would be phenomenal! Thank you!
