There is no best place to sell coral online. There are five or six different places, they are good at different things, and the one that suits you depends on whether you are thinning a tank, clearing a whole system, or trying to build something that looks like a side business.
We run one of these channels ourselves, so read this knowing that. FRAG is operated by The Underwater Gardener. We have tried to write the section on our own channel the same way we wrote the others, and we have said where it is the wrong choice.
Everything below that is a factual claim about another platform is either quoted from that platform’s own site or flagged as unverified. Fees and policies change; check before you list.
The six factors that actually decide this
- Who carries the shipping risk. On most hobbyist channels, you do. You bag it, you box it, you argue about it if it arrives melted.
- Whether anyone handles payment. Direct-message marketplaces usually do not. That means no chargeback protection in either direction.
- How much of your contact information becomes public. Forums and groups put your name next to your tank.
- How long it takes. A store answer is days. A listing can sit for months.
- Price versus certainty. Direct-to-hobbyist pays the most and asks the most of you. A store pays less and does the rest.
- Cash or credit. Only stores offer credit, and credit is usually worth more than the cash number on the same piece.
Selling or trading in to a local fish store
Best for: tank breakdowns, overgrown colonies, anyone who wants one conversation and a decision.
You bring or send the coral, the store looks at it, you get an offer in cash or store credit. No listing, no photography, no packing, no live-arrival dispute with a stranger. The store absorbs everything that happens after the handoff.
The trade-off is the number. A store offer is below hobbyist-to-hobbyist price, because the store is buying inventory it has to quarantine, hold, photograph and then sell — and it eats the loss if the piece browns out or melts. Anyone offering you retail price is not going to be in business long enough to pay you.
Where it goes wrong: stores stock to their own shelves. If they already have four torches, yours is worth less to them that week no matter how good it is. Ask before you drive.
FRAG
Best for: selling directly to another reef keeper, trading coral for coral at no charge, or getting a free store review — without your contact details going public.
FRAG is our moderated marketplace, and it supports three paths. Trade coral for coral at no charge. Request a free store review and we quote you in cash or credit, with no obligation on either side. Or sell directly to another reef keeper: the two of you agree on the price and pay each other directly. As the seller, you disclose the agreed sale amount to FRAG and pay a platform fee equal to 2.5% of that amount before FRAG facilitates the sale or connects you with the buyer to complete it. Listings are reviewed before they publish and contact details stay off the public listing.
Trade-offs: on a direct sale we do not touch the money. Like MetaReef, we introduce the two of you and the funds move between you — which means no escrow, no payment processing, no chargeback protection and no dispute service from us, in either direction. The seller pays FRAG’s 2.5% platform fee on the disclosed direct-sale amount before we facilitate the sale; trades and store reviews are free. It is not zero, so if fee is the only thing you are optimizing for, MetaReef’s stated “No seller fees, ever” is the cheaper headline and you should weigh it against having a moderated listing and a store review in the same place.
Where it is the wrong choice: it is newer and smaller than the forums, so a niche piece will see fewer eyes than it would on Reef2Reef. If you want maximum reach today, that is an honest reason to list elsewhere. And because we operate it, a store submission through FRAG comes back with our offer — which is a store offer, with everything that implies above.
Reef forums and regional clubs
Best for: named morphs, rare pieces and anything where the buyer needs to know who grew it.
Reef2Reef runs buy/sell/trade sections and local club subforums, and it is the largest reef community on the internet by a wide margin. Reef Central and regional club boards work the same way at smaller scale. A reputation you build over years is worth real money on these boards, which is exactly why they favor established members.
The trade-offs: your posting history is public, you handle payment yourself, and you own the shipping outcome completely. Selling privileges and rules vary by forum and by section — read the section rules before you post rather than after.
Where it goes wrong: a new account with no history selling an expensive piece reads as a scam to everyone who sees it, however honest you are.
Coral-specific marketplaces
Best for: listing a handful of frags to an audience that is already shopping for coral.
MetaReef states on its own site that hobbyists can “List your corals online free,” that there are “No seller fees, ever,” and that sellers “keep 100% of every sale.” It also says buyers “Message sellers directly to arrange the purchase — no middleman, no fees.” Read that second part carefully: no middleman means no payment processing and no dispute process. You are arranging a private sale that the platform introduced.
Reefables offers a free store and advertises “NO COMMISSIONS for 30 days,” which tells you commissions exist after that window — check the current rate before you commit. Its own site states that “All listings are created and managed by individual vendors” and, plainly, that “Reefables does not endorse or verify the accuracy of any product descriptions, claims, or images.” That is a fair warning to buyers and a fair description of your responsibilities as a seller.
CommunityCorals also operates in this space. We could not load its terms to verify fees or policies at the time of writing, so we are not going to describe them.
Where these go wrong: the audience is smaller than a general marketplace and you still do all the work — photography, listing, packing, shipping and the conversation when something arrives unhappy.
Facebook groups and local sale pages
Best for: local pickup, fast, no shipping at all.
Regional reef groups move coral quickly because the buyer drives to you. No box, no heat pack, no overnight window. For a tank breakdown where you want volume gone this weekend, it is hard to beat.
The trade-offs: no seller protection, no structure, and group rules are enforced by whoever is moderating that day. Payment is whatever you agree to, which in practice means you are meeting a stranger with cash. Verify the current group rules and any platform policy on selling live animals before you post — these change and we are not going to quote a policy we have not read this week.
eBay and general marketplaces
Best for: reaching buyers who are not in any reef community.
The reach is the largest of anything here and the structure is the most formal — there is a payment system, a feedback record and a dispute process. There are also seller fees, and live-animal listings carry their own category rules.
We are not quoting eBay’s live-animal policy or its fee percentages here, because both change and a stale number in this paragraph would cost somebody money. Read the current live-animal policy and the current fee schedule on eBay before listing a coral.
Where it goes wrong: a general-audience buyer has no idea what a healed frag is, what your light was, or why the coral looks different at their house. Expect more explaining and more disputes than on a reef-native channel.
Short version
- Breaking down a tank, want it handled: a store, in cash or credit.
- One rare named piece, want top dollar: a reef forum where you have history.
- A dozen frags, no rush: a coral marketplace, and read the fee terms first.
- Volume gone this weekend: a local group with pickup.
- You would rather swap than sell: a coral-for-coral trade, which costs nothing on FRAG.
- You want to sell to another hobbyist but keep your details private: a moderated marketplace. On FRAG, you and the buyer agree on the price and pay each other directly. As the seller, you disclose the final amount and pay FRAG’s 2.5% platform fee before we facilitate the sale.
- You do not want to ship or negotiate at all: a store.
If you want the store route, our review process, what we take and what we decline is written out on selling your coral to us. If you would rather trade a frag at no charge or sell one directly to another reef keeper, both of those live on FRAG.
