Amazing corals and very nice shots.
would love a bit more crisp shots so either make sure you're shooting perpendicular to the glass, or chose the thing of your shots when the polyps ain't moving around a lot or decrease your flow ... Unfortunately shutting flow completely will make the long polyps look really ugly. Flash can help but creates its own set of issues with colors. I really like the color what lighting did u use and did you post process the shots?
The efflo (although not the best shot) and the blue tort look amazing, I like the first shot the most.
