Fish Anatomy
I noticed that there are many different types of fish species and they are all shapes, sizes and colors.
Some zoomed in angles I observed the different sizes the fish are and how that affects how they swim like the shark for example has a long narrow body so he can swim fast in the water and can catch his prey easily. The smaller red fish, a rock fish I believe. The rock fish anatomy helps them fit into rocks better and find cover easier to stay away from predator fish like sharks and other bigger fish. And finally the bigger fish which i believe is the biggest fish in the entire tank is wide it has a big head with a big tail so it is not very fast in the water but is big to scare off anything that tries to mess with it and is a lot harder to attack since its great size intimidates other fish.
