Some fish are nest dwellers, meaning they build and protect a nest where they lay their eggs and care for their young. These fish typically exhibit parental care and are often territorial around their nests. On the other hand, nest scatterers do not build nests and instead release their eggs into the water, where they are left to develop on their own. These fish do not provide any parental care and their eggs are at the mercy of the surrounding environment. **
