Hi! So from what I know, goldfish are social and are usually kept in groups. At the moment I have a single Lionhead I keep in a 20 gallon. The tank is clean, fully cycled, and maintenanced regularly, so would it be worth it to get her a little friend, or is it best she go it alone? I’d say, by estimation, she isn’t even over 3” and has almost no wen growth. Thanks! Let me know what you think!
