Yes Barbel do sleep - On the river bed
Sorry couldn't resist that one. On a more serious note though, the general view, or that which I could find, on fish (not just barbel) sleeping is: - Most all fish spend time in an energy-saving state that can be called "rest", and we might even call their behavior "sleep", though it is probably different than "sleep" in most land animals. Many fish, rest on or under logs at night. Coral reef fish active in the day, hide and rest in crevices and cracks in the reef to avoid being eaten at night. The resting behavior of fish is very different from their behavior the rest of the day. Many minnows, for example, which are very active in schools during the day, scatter and remain motionless in shallow water at night. Many fish "rest" or "sleep" during the day and are active at night instead, but almost all fish sleep. There are some animals that never stop swimming, like many species of shark, however, they HAVE to keep moving to push water through their mouths in order to breathe, and they may still sleep while moving, we just don't know yet. Never give up - There's always tomorrow! |

When I used to keep fish at home, tropical and some small rudd and carp, if I went into the lounge at night when they had been in the dark for a few hours,
they seemed to be asleep just hovering in mid water and the eyes looked to be staring. They also lost there colouring and appeared washed out after being in
the dark.
If food had been present though things may have been different... |

I've read that they can't 'close' their eyes as they don't posess eyelids like we do (they don't need them as they live underwater and
that keeps their eyes moist and that's the main reason we surface dwellers have eyelids).......
Don't know if this applies to all species of fish or not though. Never give up - There's always tomorrow!

I have shone a torch down ito the margins of gravel pit at night, off a point that had lumps of concrete all over the bottom. There were dozens of small perch,
all resting with their bellies on the rocks, not moving a muscle. Perhaps this explains why perch fishing is almost always a waste of time after dark (unless
anyone knows differently). It probably isn't really sleeping, in the same way that I don't think swans ever truly go to sleep. You see them all curled
up, but they nearly always have one eye open and will react in a second if you get too close.

I dont think fish have eyelids to be able to close their eyes
although sharks have a protecting membrane to protect their eyes whilst feeding which i think is called a nictating membrane

Do Androids dream of Electric Sheep?
Then who knows what goes through fishy minds - where the next meal is coming from? Perhaps they are hooked on that? |
