Zoanthid Prices: The Per-Polyp Economics of the Hobby's Biggest Category
Zoas are the most-listed livestock on the index by a wide margin. What a fair price looks like, and why the range is so wide.

Zoanthids are the biggest single category in online reef retail, and it isn't close: 607 listings on the latest snapshot — 15% of all coral listings and 8% of every livestock listing we track, across 4 vendors. The full census is in what online vendors actually sell; this page is about what a zoa should cost.
The numbers today
The range spans roughly 23× from cheapest to priciest, and that spread is the entire zoanthid story. Zoas are the hobby's purest strain market: the animal is nearly identical across listings — small colonial polyps, mostly easy to keep — so virtually all of the price is the name and coloration of the morph. A single unnamed polyp and a limited-release named polyp are the same husbandry project at wildly different prices.
Reading a zoa price like the market does
- Per-polyp is the real unit. Listings mix single polyps and multi-polyp frags or colonies. Two listings at the same price can differ several-fold per polyp — divide before comparing, especially on "colony" listings that look like bargains.
- The median ($39.99) is the benchmark for a named-but-common morph frag. Below it live the workhorse morphs every vendor carries; well above it, the limited releases and grail names where scarcity pricing takes over.
- Names are not standardized. The same or near-identical morph can circulate under different names at different prices. If a name carries a big premium, image-search it across vendors before paying the premium.
- WYSIWYG matters more here than almost anywhere. Zoa coloration varies frag to frag and photo lighting is half the marketing; the exact-piece guarantee is worth real money on expensive morphs (the measured WYSIWYG premium).
Why zoa prices are honest anyway
A market where the price is mostly a name sounds like a scam waiting to happen, but the zoa market clears remarkably honestly: supply of any morph grows every time a keeper frags a colony, so yesterday's $200 grail reliably becomes next year's $40 staple. High prices are real scarcity, and the scarcity is genuinely temporary. The practical translation: patience is the biggest discount available in this category — and it's another reason the quiet day-to-day price behavior we measure shouldn't surprise anyone. Prices step down when supply catches up, not drift down week to week.
