In the Korean crested gecko market, Tricolors have become almost iconic. They’re so common now that you can even spot them at your local Petco. On the surface, they’re simply geckos with three colors—but that alone doesn’t explain the obsession.

So why are people so captivated by them?

A Tricolor isn’t special just because it shows three colors. The real reason behind the hype is that quality differences are incredibly obvious, making the evaluation highly competitive.

Breeders analyze every tiny detail, including:

I first encountered geckos with the Marbling phenotype around 2024.

Like many of you, what drew my attention at first was their unusual yet strikingly beautiful appearance—something that felt distinctly “different.” Out of curiosity, I began asking around, searching for information, examining examples, and before long, I found myself wanting to reproduce this phenotype as well. I gathered babies that looked similar, kept entire lines that produced Marbling-like offspring, and raised them myself.

A Lighthearted Look at Taxonomy

For reptile enthusiasts, these scientific names are probably very familiar. We use them constantly when talking about different species.

The Passion Behind “Giselle Gargoyle”

Q. Hello, Giselle! It was such a pleasure sharing the Tinley show with you. How was your experience at the U.S. reptile expo?

At first, it was honestly tough—I wanted to go home right away. The jet lag and the long, intense schedule really took a toll on me.

But on the first day of the show, so many people recognized me and the “Giselle Gargoyles,” and that gave me a huge boost of energy and excitement. After that, I completely forgot how tired I was and just had an amazing time.

Looking back now, it was truly one of the most rewarding and meaningful experiences for me.
