Ok, so I know this tank needs a whole lot more. (Especially I lid)
I definitely need to add more gravel and deco, and Both my goldfish are about 4 to 5 years old. I rescued them from Walmart back in 2018. They were dying in the bottom of a betta cup, that was less then half way full.
One is 4 inches, the other is a wopping 6 Inches! And they are currently in a 30 Gallon aquarium.
The tank is running on a Tetra 30 gal canister filter. I really want to add something else to the tank. But I can't really think of a good cold water tank mate.
But what would you guys rate my setup, and what could I improve?
(Also where can I find a good lid that isn't $60?)
