Got into a discussion today at work - someone said fish have no feelings of hurt, nor do they have a memory span of more that 7 secs. Of course I disagreed with him and told him that my fish recognise me as the blob that feeds them. I feed my fish every afternoon at about the same time and you can see them lining up at the front of the tank just at that time. Also, when we have visitors, they disappear. You ever tried explaining to people that your tank is overstocked and that I need a bigger one when they can't even see 1 itsy bitsy little bugger Yet once the visitors have left, out they come and carry on their daily routine. Surely, if they had no memory they wouldn't do things like that What do others have to say about this? I'd like to know so that I can pass on your remarks to my gourmless friend.
