Can a fish have crush on another fish?

It's impossible to say definitively whether a fish can "have a crush" in the same way we understand it. Fish don't experience emotions the way humans do. However, we can observe certain behaviors that suggest some kind of preference or attraction.

Here's what we know:

* Fish have complex social interactions: They form hierarchies, engage in courtship displays, and even show signs of aggression or territoriality.

* Courtship rituals: Many fish species have elaborate mating dances and displays, involving color changes, body movements, and even the offering of gifts. This suggests a degree of selectivity and a potential for "preference" in their choices.

* Pair bonding: Some fish species form long-lasting pair bonds, remaining together for breeding and raising their young. This implies a more sustained level of attraction or connection.

So, while it's not accurate to say a fish has a "crush" in the human sense, there are definitely behaviors that suggest a level of preference and social complexity in their interactions.

It's important to remember that we're interpreting animal behavior based on our own human understanding. We can't fully know what's going on inside the mind of a fish, but observing their behavior can be fascinating and thought-provoking.
