fishes live eggs water
Fishes in Percoidei live all over the world except for polar waters.
Fishes in Percoidei live in freshwater or saltwater. The freshwater fishes live in lakes, ponds, ditches, swamps, and fast- and slow-moving streams. Saltwater fishes live near the shore or out at sea.
Some fishes in Percoidei eat algae, plants, animal plankton, invertebrates, which are animals without backbones, and fish. Algae (AL-jee) are plantlike growths that live in water and have no true roots, stems, or leaves. Plankton is microscopic plants and animals drifting in water.
Some fishes in Percoidei are active during the day, and some are active at night. Some form schools; others live alone. Some fishes rest on the bottom. Some move up and down in the water. Some fishes travel for spawning, or releasing eggs. Some spawn in groups and scatter their eggs; others build nests to mate. Many fishes guard their eggs and young.
Some fishes in Percoidei are caught for food, and some are farmed. Many are prized sport fishes, and many are used in aquariums.
