Feed all of the baby fishes, and be prepared for some baby fish to die...
Think about this for a minute.. goldfish do not appear out of no where and they aren't artificially created. How else do they appear? Well they breed to produce eggs where goldfish fry (babies) come...
Of course they do. Every other animal have babies.
its not that big its actually like the head of push pin
If they are there, you definitely can.
