What fish are like

"Like" is a very broad term! To give you a more helpful answer, can you tell me what you'd like to know about fish?

For example, are you curious about:

* Their physical characteristics? Do you want to know about their scales, fins, gills, or their wide variety of shapes and sizes?

* Their behavior? Do you want to know about how they swim, how they communicate, or how they hunt and eat?

* Their habitats? Do you want to know about the different places they live, from coral reefs to deep oceans to freshwater streams?

* Their role in the ecosystem? Do you want to know about their importance as food sources, their impact on other species, or their role in keeping the water clean?

Once I know what you're interested in, I can give you a more specific and interesting answer!
