Help a brother out. The beautiful Chilli Coral which I received three days ago is in shock. After the first day, I went to bed with Chilli flying all his feathers. When I woke in the morning, like a kid at Christmas, I peaked into tank with a red led flashlight. It was collateral damage. The complete rock wall with ledge for shade had fallen down on Chilli. With no external abrasions, I brushed off detritus on Chilli and remounted in a different place. After 24 hours he showed a few feathers, but not so this morning. He is covered in detritus that seems to stick to outer skin.

Because of the aggressive sand bed maintenance that is ongoing, Detritus is getting stirred up more than normal. In the case of the Sea Apple, he worked overtime to capture detritus as food. Do the feeding requirements of Chilli and Sea Apple contradict each other? Surprisingly, with all the sand bed maintenances on Jaubert Plenum, the refugium is crystal clear with no carry over of detritus. I credit that to the first chamber on this eco-system mud/macro refugium. In looking at the rocks in refugium, there is no detritus to blow off.

IMO, this might be the best hospital for Chilli.

I wish we knew that answer to that! (Maybe Steve has some thoughts?) As a group sponges are going to be just like stoney corals and soft corals - some do well in our systems but most are still beyond our ability to keep because we still do not know the specifics of their husbandry. And I suspect it's likely a lot of sponges eat something else besides or in addition to DOC. De Goeij showed certain cryptic sponges in his thesis removed bacterioplankton from the water, what if these are "omnivorus" and some sponge species need specific types of bacterioplankton or DOC?. Just like we can't keep a lot of Acro species because we don't know enough to replicate their environment most of the sponge species are still beyond our reach.

Sorry to hear about that! Chilli's are still beyond our reach, it's not one I know any one has been able to grow and frag.

“Chili’s are still beyond our reach”. Does that mean it was better to die in a rock slid and not be prolonged to death by starvation?

The two NPS Gogorgions are looking good, particularly the Yelliw Tree Gorgonion.

Cryptic Zone Hospital

After 16 hours in the unlit mud / cryptic zone refugium, Chilli is looking good under old macro refugium bulbs.

Red Hot Chilli Pepper

Chilli update

After nearly 48hour in cryptic zone refugium, Chilliís color has gone from maroon to a vibrant red, as he was in shipping bag.

Due to continued sand bed maintenance, detritus continues to be stirred up. Not good for Chilli. Chilli stays down under for another week.

Chilli might think its cool in the cryptic zone & might like to make it his home?

Just started on a cryptic zone sump design.

Have built a permeable dividing wall - semi cryptic/cryptic zones

Made from coral rock, coral gravel, white cement & rocksalt.

Maybe for a short time of < 3 months. By then my algae feeding platform will have filled in providing the shade that Chilli requires. Also, my sand bed maintenance should be completed eliminating particulates clogging up Chilliís feathers.

Hi steve, I've read cmat vol 1 & 2, at least the parts that apply to what I'm attempting to do. I'm using a permeable coral rock dividing wall to seperate a semi cryptic / cryptic zone in my sump. I was planning to slightly illuminate the semi section.

My problem is I have no access to dedicated cryptic sponge rock.
The best I can do is to use some rock from within my display that has sponge life on it to seed the cryptic zone. These sponges get zero direct light, but some indirect illumination. Will these sponges be ok or not?

I don't want tp place them in a cryptic zone only for them to die & possible pollute the system. Should I perhaps just make the sump fully semi cryptic??

cheers

Twin,
I feel that my mud cryptic refugium is semi-cryptic because the whole back of stand is open to air flow and ambient light.

I have also included a 3G chaeto refugium in display tank overflow box. I figure the production of DOC and micro algae, a type of phytoplankton.

“Marine phytoplankton are mainly composed of micro algae known as dinoflagellates and diatoms, though other algae and cynobacteria can be present”.
