"Humble.fish & Reef is a diverse reefing community working together for healthy fish and all things reefing."
On this site they have a list of, "Quarantined Livestock Vendors
Companies that sell fully quarantined & conditioned fish, corals and inverts."
I think "fully" quarantined may be a bit misleading as in the real world nothing is perfect and stating "fully" may lead people to have higher expectations than reality allows, but the idea behind this is sound. I know people who have kept fish isolated in a tank for 2-3 days, performed no prophylactic dips, and then claimed they were "quarantined". The vendors on humblefish that fall in this section go above and beyond 99% of the rest of the vendors in the industry and are thoroughly and continuously vetted by Bobby who goes by "Humblefish".
The humblefish forum can be a very friendly and helpful place for an assortment of reefing questions. Certainly a step above most other forums and facebook groups I belong to. The site is certainly at this time a better resource for fish disease questions than any other site I have seen.
As of 12/21/2025 TerraReef is the only vendor selling corals on the site. We became a QT vendor on the site in April 2022, but have been quarantining all of live stock that do not come from a trusted vendor since well before 2011.
