Requesting information

[Ahmed Attia]

Answers to my questions will be very appreciated. I must confess 
that I do not know anything about fish, so that please forgive me if 
my questions seem to be silly..

Do fish have internal ears?  how fish can hear ?   If they can 
produce voices then I assumed they can hear someway maybe 
through water vibration, And  can fish recognise other fish like for 
example lions who can identify each other.

Lastly, Can fish distinguish between colors the same way we do or 
they have simple eyes that they can not see color differences ? 
THANK YOU ...
