Everytime I do a water change on my tank, whilst re-filling all my Ellioti Juvi's do the strangest thing.
They line up one behind the other in a corner or along the tank edge heads down, noses literally down in the sand and stay there, motionless until its finished, then afterwards, swim around as though nothing had happened!!
I dont know why and no other fish Ive ever had has done this, just wondering if anyone else has seen this behaviour before or whether its just my mad fish?
