That is called "clamped fins" and is sort of like a frwon, it does mean
they are unhappy, check the water quality and filteration. Is the tank overcrowded now that they are grown? Dirty filter? Heater not working? Start investigating.

Hi all,

I was just wondering if anyone out there knew about fish swimming with
their top fins down. I have a tank full of goldfish, fantails and
black moores and they have started swimming with their fins down for
some reason. They don't look sick and they have lots of energy. They
are eating well and look healthy except they have started swimming
with their fins down.

If anyone has any suggestions why this is or knows what might be
causing it I would appreciate a note.

Thanks

Hiya,

I'm relatively new to all this but from the experience i've had so far
has led me to believe that when the fishies' top fins are down it's
because they're generally p#ssed off or ill. My moor & oranda are big,
fat healthy looking fish and yet their fins go straight down whenever i stress them out by vacuuming the gravel or basically invade their space
too much for too long!

If they're ill then other signs should present themselves soon enough
to help you diagnose the cause. If not....then it's probably best not
to worry too much...give them time.
Hope this helps :o)
