And that is why I dive
My last dive in Grand Cayman (at Trinity Caves) I came over the wall from 100 feet, up and around a huge coral pinnacle. At the top of the pinnacle at 70 feet deep there was that many blue reef chromis mixed in with a ton of creole wrasse, which are almost the identical blue. I could have sat there for the last 40 minutes of my dive. It was amazing!
In Cayman the blue reef chromis are so beautiful...almost under appreciated in a fish tank because you can't have hundreds of them

My son has always wished he could have a huge school of the blue reef chromis in his tank but he was told they would fade in colour in the fish tank.
thanks for the vid...If you like that, you should watch the TV show Descending. It's awesome!
