[citation][nom]cracklint[/nom]fish don't have feelings . the eat, poop, and procreate. I seriously doubt they care how much room they have to do it in, as long as they can do it. If they do have feeling they probably are glad they don't have to worry about being eaten by natural predator typically not found in fish acquariums. You have watched Finding Nemo way to many times.[/citation]
No offense, but you're an idiot.
I haven't even seen Finding Nemo, but I've had fish for over 40 years. Can you even count that high?
Fish can think, that much is clear. I have trained one to pop the thermometer when she wants food, and then twirl. She's very cute, and beautiful, and very smart. She recognizes me, and will not perform this trick for anyone else, because she knows she will not get food.
Did you know Cichlids protect their young? Did you know the parents communicate with each other? Did you know they are capable of recognizing another fish they haven't seen for a year? Did you know they can change color in seconds based on their mood? I'm guess you didn't, but you spoke like an expert anyway. If they don't have emotions, how can their change color to reflect their emotions? How can they get so excited when they see a human and think they are about to be fed? Excitement's not an emotion?
Fish DEFINITELY have personalities. You can get 10 fish, and some will want to work with you, and will let you touch them, and such (not a great idea though, unless you "slime" your hands first), some will not. Some will watch you, some will be indifferent to you. Some will be extremely aggressive, some will be passive.
The point is, you know nothing about what you're talking about. Some fish are stupid, and have little personality, but there are some that are quite smart. They have to be, it's a big advantage for them. In fact, the female I am talking about is a Tilapia Mariae, and they are so successful a species, they are illegal in many states because they will take over the regions and knock out the indigenous species. This is because they are so smart, and so aggressive. They are also extremely beautiful as adults.
