I wouldn't start even a baby in less than a 500 gallon round pool.... even 750 or more would be better. I have yet to see a healthy adult that was raised in a standard glass/acrylic aquarium.
But even then, so many that have them die on them at small sized won't invest the time/money into getting a real cause of death. They just toss them out or dry them as a mount for their shelves. Nothing wrong with that, but it makes it hard to learn what steps to take next time. I'm all about learning what happened so that info can be shared.
The last two I delt with that were raised in small glass tanks both ended up with weak vessels in their hearts which lead to ruptures causing internal bleeding/heart failure. A pair prior to that were lost due to liver/renal failure after not having enough room to swim. Swimming is a very important part of the fish's ability to digest and metabolize what it is being fed.
