Can fish eat other eggs?

Yes, some fish species are known to eat other fish eggs. This is called oophagy.

Here's a breakdown:

* Common Practice: Many fish species, especially those with limited food resources or in crowded environments, engage in oophagy. This includes fish like catfish, bass, and sunfish.

* Survival Strategy: Oophagy can be a crucial survival strategy for these fish, as eggs are a readily available source of nutrients and energy.

* Predator vs. Prey: Even species that are not primarily egg eaters might consume eggs opportunistically if they come across them.

* Parental Care: Some fish species, such as cichlids, exhibit parental care and protect their eggs from predators, including other fish.

* Competition: In environments with limited resources, oophagy can create competition among fish, especially those belonging to the same species.

It's important to remember that not all fish species are egg eaters, and some fish actively protect their eggs from predators. However, oophagy is a natural phenomenon that plays a significant role in the survival of some fish species.
