How do fish tell their kids apart from other fish?

Generally speaking, they don't. Most fish lay eggs and then leave them without any further care.

J. Elliott

Many fish parents do not take care of their fish after they lay the eggs. Except for a few exeptions, the parents will guard the eggs, but once the eggs hatch, the baby fish are on their own.
