i know this sounds like a stupid question but i’m worries and don’t know what to do!!
i bought 4 goldfish yesterday and they all seem to be fine so i don’t think it’s a water issue
however my little black fish dolly is being really weird, staying at the bottom of the tank (usually in far corner) floating upside down/on her side, very jerky movements and erratic twitches etc, sometimes doing a random v fast jerky loop the loop thing,
am i doing something wrong? is she just adjusting to her new environment? it doesn’t seem very normal :(
im very worried any advice appreciated
