SCIENTIFIC, ARTISTIC TOOLS THAT MAKE YOU THE TALK OF EVERY GATHERING
No more guessing, no more “that green one” — my work gives you instant confidence in naming, placing, and showing off your corals.
From Zoanthids by Christina posters to the Hexacorralia identification guide, every piece blends marine science accuracy with gallery-level photography.
These are not just references; they’re conversation starters. Whether you’re at a frag swap, hosting friends, or posting online, you’ll stand out as the reefer who knows their stuff and has the art to back it up.
MEET THE MAKER
Hi, I’m Christina Rene Duncan — a marine scientist, taxonomical photographer, and lifelong ocean advocate.
Born from late-night coral shoots and hands-on fragging, Hexacorralia and Zoanthids by Christina are photographed on my Nikon D850 with a 105 mm macro. Grounded in UF marine-science training and 20 years owning and operating AquariumDepot.com, these references pair scientific rigor with gallery-grade presentation.
Every poster, print, and guide I create is made to be more than a product — it’s a way to connect people to the ocean and to each other. Want to read more? All about Christina

THE POWER OF PATTERN
Hexacorralia ID teaches you to see like a taxonomist: corallite spacing, septa counts, polyp form, growth habit, and skeletal texture. Quick-scan callouts and rules-of-thumb for light/flow turn “guessing” into repeatable decisions—no more ID paralysis.

SCIENCE YOU CAN TRUST

Frequently Asked Questions
WHAT SIZE SHOULD I CHOOSE?
Use the ⅔ rule so it looks intentional, not tiny.
Measure the furniture or wall span. For art above a sofa or tank, pick a width that’s 60–75% of the length below it. Hang so the center is ~57" from the floor or 8–10" above a sofa back. Panoramas love long walls and hallways; small spaces shine with a single Volume.
WHAT IS IT PRINTED ON?
Museum-grade paper + pigment inks (archival).
We use acid-free, archival paper with pigment inks for crisp micro-detail and long life. Optional UV-safe laminate adds wipe-clean durability for fish rooms and classrooms.
WILL THIS ACTUALLY HELP ME PLACE CORALS?
That’s the point—pattern recognition at a glance.
Each Volume teaches you to see like a taxonomist—corallite spacing, septa, growth form, and texture—plus light/flow rules-of-thumb by family/genus so you place smarter and avoid “guess & bleach.”
WILL THE COLORS MATCH MY SCREEN?
Calibrated to sRGB—minor shifts are normal.
Screens vary. We soft-proof in sRGB for consistent, punchy color, but slight differences vs. your device are normal. Expect prints to look richer and more detailed in person.
DO I NEED A FRAME?
Recommended—UV acrylic or a clean poster frame.
Frames protect detail and color. We like simple black/white frames with UV acrylic. A 1–2" mat gives it gallery presence; poster rails work for a minimal look.
