My petsmart rescue cosmo officially moved into his very own 20 gallon! I had 11 goldfish fry in here but rehomed them all 3 days ago, after that I cleaned the tank and set up a heater, let it all sit for a few days then decided to move cosmo to it instead! I think its perfect! All the parameters checked out, and this tank has been up and running for over a year so much easier than buying a new 10 gallon, and waiting fot it to cycle! (He was in a 5 gallon) I hope he likes it as much as I do!
