Ohhhhhhh my opinionated but bouta start a fightttt
Fish act on instinct
Instincts are not emotional
Instincts are the act on what has been proven to keep your species/family/you alive. Fish will act “happy” Because they see you as a source of food, do you know that when they do this they are seen as “cute” and they will get food. You are nothing to them except for the provider of their food meals stress confinement and slow torture. The fish that you currently have in your tanks are dying, all fish and all living beings are dying that is what age is. You are confining this fish or the fish that you own to this area they know nothing else, they only know that you are the source of their food that is the only reason they react to you in anyway. People used to say that elephants reacted neurologically when they saw someone they knew the same way a person does when they see a puppy . This is not true has never been proven to be true and it was never an actual fact I believe it is the same way with fish. Because we cannot get a fish a CT scan to see his brain activity. Compare the size of our minds or any other animal that can feel proven emotion or connection to other beings of its species or outside of its species. It is a small small small small minded fish. And I’m just gonna go right down and say it your fish and all fish are dumb. Your fish is relative Git themselves caught and then they were bred over and over to result in your fish. Or fish was just stupid and got snatched right from its home. Your fish can never and will never feel emotion or connection to you period
And I adore my fish but I will never say she has emotions. If I offended you then do your own research
I believe you are incorrect in the fact that connections cannot be made between fish and people. As I see it, my fish must have a depth of trust in me, beyond a food source as I can net them with ease. There is no thrashing or chasing or fighting. When I present the net to the one I want, it swims on in with no fuss (sometimes others swim in too, like where are we going to go?) Many fish in my care are quite old. Not a couple years old, but several years to a decade old. They are not stressed as they move gracefully through their tank. I know this by their color, their activity, the way they interact with their tank mates, their environment and with myself. They recognize my family members. My father in law does not live with me but he comes to visit as well as tank care of the fish while we are away. They see him and they immediately begin to wiggle and glass surf until he comes closer. They recognize him. They also recognize and respond differently to each of my sons. Beaker, my Blood parrot absolutely adores the attention of my 21 month old. He follows him around the tank and when my toddler has his face close to the glass, Beaker is right there, looking him in the eyes. My toddler doesn't feed the fish, he is an observer, but they have bonded. It happens all day, every day, as soon as Beaker sees his buddy, he is there following my son's every move. I can list hundreds of similar interactions between my family members and fish, heck, even other household pets and the fish.
It is a bit unfair to call fish stupid because they were caught in the wild, many fish caught in the wild are "easily" caught because humans employ nefarious means to catch them. I mean if you are going to drug a whole section of river or stun the fish, it is not the fault of the fish it was caught. Humans if stunned/drugged could be just as easily taken.
Humans are animals after all, we have a terrible habit of believing we are bigger and better than everything else. I will not see my animals in any other light than what they show of themselves to me. My goal is to give the best life to all my pets. I believe they show their love in their own unique way. My bonds with my fish, cats, dogs are all strong and I am very attune to how they are feeling. They aren't just " Cats, Dogs, Fish" they are living just as we are, and have their own feelings. Maybe not a capacity for critical/logical thinking (I often question humans capability of this at times, too) but certainly capable of basic emotion.
