This new mother colony has a little barnacle embedded in the skeleton and the irritation to the coral causes a localised collection of green fluorescent protein (GFP). Commonly called a GFPI, where the I refers to the proteins being an infection. This is generally noticed more on new growth or a growth rim of corals, but like this one it’s kind of like new growth in that the coral is healing and depositing new tissue at the site of irritation from the barnacle. It’s unlikely this green will spread and cause a “grafting” type appearance but we’d be mad not to encourage it!

Random green streaks like in the “mystic sunset” Montipora in picture 3 are commonly called GFPIs.

Some fresh pictures for your hump day viewing pleasure. Another wholesale website update was just done, these are included…. And the acid swirl has been unavailable for DONKEYS YEARS so it’s great to see this old favourite again.

Tri colour grafted cap (just the one pictured so its WYSIWYG), forest fire rhodactis, acid swirl Monti, Gauva zoas, blue sympodium, zoa hex tiles, Thanos rhodactis, sinularia & nepthya, plasma psammocora & yellow polyp turbinarea.

Happy Friday everyone! We hope you had a great week and if you’re heading into the weekend for some relaxing downtime with your reeftank here’s some fresh pics of stock that was loaded into the wholesale website. Let your LFS know if youd like anything ❤️🪸

Spawning corals isn’t really that new, especially when we don’t actively set out to do it. If it happens it happens, if the babies settle and grow then we make an attempt to isolate and nurture them. In saying that, it’s always nice to see multi generational spawning! Especially in corals that are only 18 months old themselves. This is interesting for us to record that they reached sexual maturity so young.

The “grandparents” being the parents here is highly unlikely for a number of reasons. Firstly they are in a separate raceway that if they spawned it would have to travel through 3 layers of mechanical filtration, a pump impeller and then into a giant UV steriliser and a bunch of other literal ups and downs before making it to the raceway where the ones from March 2025 are.

Also… no other babies have been found in the raceways that don’t contain torch corals and the grandparents don’t appear to have any new babies in their own raceway so that in itself proves they are now F2 spawned torch. Exciting stuff! Now to stick some RFID tags in them to further track this growth.

Gooood afternoon everyone. It’s been a busy morning fragging, so we were able to update the wholesale website with fresh stock quantities. Still a bit light on in some areas but stock is gradually building to numbers that will satisfy everyone. Thank you for being patient. An example below of the zoas on offer this week.

If you are a retailer and have not yet received your unique login details for the website, please reach out to us to get involved.

Corals are weird. Believe it not….. every single one of these zoas is a self replicated clone…. Yep, all these variants including the highlighter yellow frill one that is the newest version of a single zoa frag made a few years ago.

Thought to be “blue or**sm” originally but no matter where they go in the system, no matter what lighting or chemistry they are grown in they continue to change, revert, morph, morph back and forth etc. this is not a case of they are changing colours under different conditions, these are side by side in groups of at least 20 multi-polyp frags and each group is behaving the EXACT same way. These changes can be as fast as 2-3 days from one colour to the next.

We cherry picked these 9 in the first image to show the variation better as a smaller group. The following images are just for a closer look. Some frags you can see the classic blue or**sm colour (blue with green grill) among dramatically different clones of itself, some polyps are clearly in a state of change between the variations.

This has been observed for at least a year, maybe more. The observations have not changed until today we noticed that super bright frill version and yep… that’s a new variant 😂.

We wanted them to stabilise on a colour so they can put them on a stocklist again, but also happy to watch them morph for a while longer.

Good morning reefers! Wholesale website stock levels just updated. But we are continually fragging so if you need something and don’t see it, don’t hesitate to ask about availability. Keep an eye out for these 3 just added to the list too. Oulophyllia levis, Rhodactis forest and Dipsastraea.

If you are a wholesale customer and still need a login, please let us know.

Happy reefing 😁

The other day we added a handful of new [to our farm] species of Acro like this one we are fairly certain is Acropora secale. After having its resident acro crab (Tetralia nigrolineata) carefully removed and put aside, the colony got cleaned up of any rock beneath the coral tissue including having a small amount of living tissue at the very edge removed to ensure there are no hidden acro eating flatty eggs waiting to hatch and cause grief! Inside the colony is also checked for dead patches caused by the flatworms or many other critters such as boring mussels, limpets, gorilla crabs that cause a dead spot where flat worms will lay eggs. Fortunately this perfect colony had nothing like that so lastly the coral is dipped and vigorously shaken in Coral Essentials flat worm dip to remove any hatched or adult flatties.

Then the colony is glued to one of our acrylic base plates with an RFID tag registered to our system and the acro crab is placed back into the coral to once again protect it from anything nasty. See the comments for the finished piece.

STI - Scleractinian Trapezia Infestation. The only type of crusty (Crustacean) STI you want on your coral. Helpful little crabs, some of them may not actually be Trapezia crabs, crab identification isn’t something we’ve spent a whole lot of time on but we love these critters, and firmly believe that if you can retain them in colonies then there is a positive impact on the coral. On the rare occasion we add new wild motherstock to our grow out system, they are meticulously cleaned of anything present that is not the coral itself or any beneficial commensal or symbiont creatures like these Acropora crabs.
