TerraReef's story

After completing his undergrad at the University of Delaware, Jon Gordon started farming coral.  Due to the 2008 economic recession, TerraReef pivoted from aquaculture to aquarium design, installation, and maintenance.  While not the main focus of TerraReef, the production of clean sustainable coral never stopped.  100% of the corals sold to our aquarium service clients were colonies grown out in our tanks.  

In late 2019, we started to ramp up production of our aquacultured corals.  2020 immensely impacted the service side of our business and a quick pivot back to farming became critical to keep TerraReef strong.

System information

Most of the corals sold on TerraReef.com come out of the same system as Jon’s personal display tank.  This 940 gallon modified Triton system uses some of the best equipment available in the industry and is watched over very carefully.  Most corals listed on our site have had 4-6 weeks to recover from fragging and have started to grow significantly.  


We try our best to reduce waste, lower our carbon footprint, and source sustainable materials when possible.  These aren't just catch phrases we're using, but something we believe is important.  

Hitch Hiking Coral


All new corals and other invertebrates introduced to our systems have been quarantined for two or more months.  We intensely observe these aquariums for pest, we almost always dip, and we'll usually remove all rock and plugs in an attempt to only add the coral to our systems and nothing else. 

We still recommend everyone quarantine corals from us and everyone else.  We can confidently say that no flat worms, Aiptasia, Majano, red bugs, pyramid snails, rice snails, or nudibranchs will be included with your order.  It is possible some critters you may not want will be included such as asterina sea stars, bristle worms, and vermetid snails as they are present in our systems.  All corals for sale have been with us for a minimum of one year and most over ten years!

If you have any questions please feel free to reach out to us.
