Here are some examples:
* Desert Pupfish: These are typically olive green to brown with darker stripes or spots.
* Salt Creek Pupfish: These have a more silvery-grey color with darker blotches.
* Speckled Pupfish: This species is known for its bright orange to red coloration with black speckles.
So, there's no one "normal" color for pupfish! It all depends on the specific species and their environment.
