Marketplace rules
Read before buying or selling. Tulamtharn is a place to post listings — buyers and sellers agree on price and pay each other directly.
Never allowed
- Wild-caught fish and aquatic animals (the listing form has no such option)
- Species protected by law
- Alien aquatic species the Department of Fisheries bans from keeping or trade
- Medicines, antibiotics and chemicals
- Aquatic plants collected from the wild
Species in the site catalogue carry a trade status the team sets after checking official lists: "Banned" cannot be listed and existing listings disappear at once · "Caution" sellers must state the origin clearly
Not sure a species may be sold? Do not post yet — ask the team first.
Who can sell
- Members the team allows one by one. Ask for permission on the My listings page (you can ask again every 30 days).
- Member listings are checked by the team before they appear. Edited listings are checked again, except a price cut.
- An ordinary price cut keeps the listing in the market. A cut below one third of the approved price, or a change to free, sends the listing back for review first, because scammers use that as bait.
- A listing lasts 30 days and can be renewed once a week. You can have at most 20 active and waiting listings.
- Sellers must be 20 or older and accept these rules before their first listing.
- Do not put phone numbers, LINE IDs, links or bank accounts in a listing. Buyers contact sellers through the site chat.
Money, meeting and delivery
- Tulamtharn does not take payment for sellers and is not a party to the sale
- Meet in a busy public place and check the item before paying.
- Never pay a deposit to someone you have not met or traded with before.
- Before transferring, check the account name matches the seller, and keep the chat and transfer as evidence.
- For live animals, agree on packing, shipping and what happens if they die on the way before you pay.
Common scams
- A price that is far too low, with pressure to transfer quickly before someone else buys.
- Asking for a deposit or shipping fee first and refusing to meet or show the item.
- Asking to move to LINE or another app outside the site, or sending links to click.
- Sending a transfer slip and saying the money was sent — sellers must check the bank app themselves; slips can be faked.
- Pretending to be Tulamtharn staff and asking for your password, bank account or a transfer — the team never does this.
- The account name to transfer to does not match the seller.
If something goes wrong
- Press "Report this" on the listing page and pick a reason such as "Scam or fraud" or "Banned item or protected species".
- In a private chat, report the message or the person, and block them right away.
- The team can hide listings and remove selling permission from scammers, but cannot refund you — money never goes through the site.
- If you have lost money, report to the police quickly and keep the chat, slips and listing link.
