Hello everyone,
You'll notice that there is a fish and invert swap forum now. You can buy/sell/trade/giveaway fish or inverts there. Review the rules carefully, aquarium co-op is not responsible and won't step in. You need 50 meaningful posts on the forum to see that forum. It also won't show up in the topic feed as I don't want buying/selling to become to main topic of this forum. The goal is to allow hobbyists to rehome stuff, sell off some extra fry etc. Maybe make enough to support their hobby. Competitors are not allowed, and full fledged businesses aren't either. If you have a website or retail store somewhere else where you are selling stuff, you're a business and not a hobbyist.
If you sell to local stores, friends, family, etc. That is not a business. You breed/buy the fish with the intent of keeping them as pets, not buying and reselling.
You can use the trader feedback once a transaction is completed. Threads where people are calling each other out, fighting etc. Will just be locked. This is very much a don't ruin this for everyone situation. This is a soft launch where only forum people will know about it. Lets not make this a regret to facilitate this.
