Create and light a saltwater reef aquarium that is healthy and looks great too.
Investigate a variety of plants, fish and coral that can live in saltwater aquaria. Choose a few to live in your tank then decide how to light the tank so all of its inhabitants thrive.Fish Reflection Spectra and Colors
This is a colorful Regal Angelfish. We see different colors in the fish’s patterns because they reflect different amounts of visible light at different wavelengths. Let’s investigate the reflection spectra from different parts of the fish and try to identify the colors that go with each one.
