Contrary to popular believe, goldfish can actually out grow the bowl they are kept in.
Most fish are indeterminate growers. Meaning, they can grow until the day they die.
It turns out, what’s more important than the size of tank is the quality of water and nutrition–Are they well taken care of? The size of the bowl has nothing to do with it.
We get it wrong with people too:
A) We can grow larger than the expectations people set on us. Larger than the culture and environment we grew up in.
B) We can also continue to grow until the day we die too. Not physically of course. But there is no end to the lessons we can learn.
