Our story

Rare corals, honest photos, real advice.

We specialize in premium corals, invertebrates and expert aquarium services, all with one goal: vibrant, healthy reef tanks. We?re here to bring the beauty of the ocean to you.

Most of what we sell is aquacultured, and many pieces grow in our own systems for months before they?re listed. Some of our frags have been tank-raised for over a year, and one Ricordea has been with us for nearly two.

Because visits are by appointment, every one is one on one. There?s time to ask questions, see pieces under our lights, and leave with a plan, whether it?s your first nano or your fiftieth frag.

Beyond the shop, we design, install and maintain aquariums for homes and businesses, and now care for ponds too.

?We specialize in rare and unique corals from all around the globe.?

Tank it easy.

From our tanks to yours

How a coral gets to you.

Every piece takes the same path through the Cavern.

  1. Ultra Goblin Goniopora polyps1

    Sourced with care

    We bring in rare and aquacultured corals from around the globe.

  2. Coral frags on ceramic plugs on a frag rack2

    Grown in our systems

    Frags settle on their plugs and grow under our lights, some for a year or more.

  3. A red and green Acanthophyllia photographed in our tank3

    Photographed as it is

    We shoot each piece in our tanks. The photo is the exact coral you get.

  4. Goniopora Garden frag with red, yellow and violet polyps4

    Matched to your tank

    We?ll tell you its light, flow and placement needs before you buy, and a care guide comes with your order.

  5. A reef aquarium glowing in a living room5

    Home with you

    Pick it up by appointment in West Salem, or we pack it for the weather and ship it.

What we stand for

Four things we won?t skip.

Small shop, high standards. These hold for every coral, fish and service job.

Honest photos

Every coral is photographed in our tanks. What you see is what you get.

Aquacultured first

Tank-raised corals settle in faster and leave wild reefs alone.

Advice before the sale

Not sure it suits your tank? Ask. We?ll talk light, flow and tankmates first.
