Red Sea is WAY more colorful underwater than the Caribbean. Caribbean is very limited with the soft corals and anenomes, Red Sea has far more variety of corals and fish. I have been to both Bonaire and Roatan (both great places in their own right) but you’ll see...the Red Sea is just different. Although I have to say of all the places I’ve been, Indonesia had the largest level of diversity...it’s really like sensory overload.
