Will a fish with the sole purpose grow to fit it's aquarium? ?
If I buy a fish that gets to be 8 to 10 inches long and keep him in a five gallon cistern will he stay small. I know that I will have to do frequent water changes to maintain him healthy.
I've have many fish, they WILL adapt. Think about it...A catfish domesticated is not drastically big.go to a lake...Catch a catfish, he will be bigger than the one you have at domestic.NOW go to a RIVER and get a catfish, he'll be even bigger than the one from a lake. Humans aren't indistinguishable as fish, they don't adapt like a fish does. They will not die a painful disappearance and they're organs wont continue to grow. All my fish are happy and healthy, Keep up beside the water changes, and you should be fine.
No. If you were placed contained by a 3x3 box for your entire life, you wouldn't grow to fit the box. That's just a bunch of BS that pet stores tell you so you buy their fish. If you expect about it, there is no possible reason that a fish would be capable of posses such an adaptation. Don't take this the wrong way, I'm not trying to insult you or anything. When you put a big growing fish contained by a small tank, you stunt its growth. This might sound ok, since it's just not growing, but that's not the defence. When you do this, the fish's body and skeleton stops growing, but their organs keep growing. This leads to a premature, slow, painful passing from organ compression.
They DON'T adapt to fish tanks. Just think more or less this scientifically. Why would an animal posses the ability to adapt their size to the box they are kept in? In spirit, this would be completely useless, and that's why they don't have that adaptation.
Besides, why would goldfish kept in bowls live MUCH shorter lives than those kept contained by ponds?
Answers: a fish will grow to the Weight and the capacity of the water surrounded by your tank as long as they can swim freely it will be fine. id get a larger container anyway depending on the type of fish you want if you bye them as juveniles and let them grow into your reservoir they are fine its when people bye them big and put them into a small tank that's when its considered cruel
His growth will be stunted and the fish will die. Buy a betta whether you want a fish to go in your 5 gallon tank.
No. He will die. Simple as that. Compare a goldfish thats lived in a bowl to one that lives in a 125 gallon tank. Which one lived longer? Some fish will stay small, but they will die not long into their lives. Other fish will grow regardless of the container. So basically, dont buy the fish if you arent going to be responsible with it.
