Bid live on coral frags, cultivars & rare livestock.

Each auction has a hard close timestamp set by the vendor. Default duration: 24 / 48 / 72 hours.

Set your maximum. The system bids the minimum increment for you up to that ceiling. Other bidders never see your max.

If a new bid lands in the last 60 seconds, the close time auto-extends by 2 minutes. Repeats until bidding actually stops.

Vendors can set a hidden reserve. If the high bid doesn't meet it at close, the lot doesn't sell - no obligation either way.

Some auctions include a BIN price. First buyer to hit it ends the auction immediately and wins the lot.

Star any lot to track it. We'll email you 1 hour before close if you've been outbid or have a watch on it.

Every winning bid uses the same DOA window + carrier-tracked Buyer Protection as fixed-price listings. Auctions are not "as-is" - the live arrival guarantee is the same.

Win the auction, pay within 24 hours. Vendors ship per their normal schedule (climate-aware Tuesdays/Wednesdays).

Every bid is logged with IP address, browser fingerprint, and login location. Accounts sharing a network with the vendor are auto-blocked from bidding on that vendor. Suspicious bid patterns (new accounts only bidding on one vendor, last-second escalation from vendor-adjacent IPs) trigger review. Confirmed shill bids are voided and the bidder banned; vendors caught running shill networks lose their account permanently.
