Fishing and fish farming
If fish refers to you, what the girl wants to express is that you are just her ambiguous friend (spare tire). Don't treat her intimate language and behavior as love or love relationship. To warn you, don't have delusions, you are impossible.
The extended meaning of fish farming in network language means that fish farmers are very philandering, keep ambiguous and intimate contact or behavior with many opposite sex, and enjoy this state of non-specific emotional possession. If this fish pond is big enough and there are enough fish, then this fish pond can be regarded as an ocean, and the fish farmers are also called Neptune!
