A bunch of new changes in the tank! We fragged out half of the SPS to stop war and give space for growth and then ended up getting some new stunning corals from a coworker. But most importantly, our beloved cowrie - Rangoon - has adapted to the new light schedule (featuring classic glowing blues at dawn and especially dusk) by coming out at crepuscular hours! He is a hard worker and it is always awesome to see him - especially with glowing coral in the background.Cowry_on_prowel.thumb.jpg.be858eac01154c7e3c52fbaf9b2bb467.jpgCowry_on_glass.thumb.jpg.26673edb8cf9dc1cf66a6ed71d45d12d.jpg

A few weeks after a massive fragging event, new corals and new light and the tank is definitely thriving. The AI fixture has things exploding with color and growth. For example, that superman we thought we had is definitely a rainbow. Looking down from above reveals the extent of the fragging and the pretty new colors:HeavilyFragged.thumb.jpg.d487b658e2fbd77c67c2924c4e350c2a.jpg

 

The new acro is even coloring up and encrusting the glue as well as popping out new polyps. It should be beautiful. Pale purple now with bright yellow growth tips and big hungry blue polyps.heavyFraggedOS.thumb.jpg.343cfdafd19a5145904effdb8783f723.jpg

 

Speaking of polyps - we are having a hard time with ID on some of our new acquisitions.

These are a crazy metallic green core, with a blue mouth, a deep blue spade shape, a light blue grey layer, and metallic green flecks on the skirt. Any ideas?

Similarly, these have colored up with the new light. They are an absolutely iridescent pink and white that turns pale pink under heavy blue spectra. No idea...

 

Lastly, these are maybe laser lemons? Green skirt, blue layer, pink layer, dark band, lime green mouth:LaserLemons.thumb.jpg.df75cfa63f28ce67ca8430794800d39c.jpg

 

Thanks for the help!

The second one looks like AOGs (Armor of God) zoas. Not sure what the first & third ones are, but I love the color on the third ones. So pretty. 🥰

The tank has universally recovered from the mass fragging event, although the whammin watermelons and fiestas caught something and went thru a hideous shrinking and partial bleaching event. In addition, I was out of town for a week and the newest acro encrusted past its glue, grew a wedge between the glue and the rock, and toppled onto the mystic sunset. It turns out the acro wins that battle, and the mystic is now recovering from partial digestion where the two made contact (5 spots). I remounted the acro with a more liberal use of glue and it is recovering and starting to recolor. All of the coral has continuously enhanced its color after the light fixture change as you can see beautifully from the top down:

The placement of the newest zoanthids was... suboptimal - so that got switched up and they are now jammed together in a happy little rainbow in the front corner of the tank:

The scrambled eggs are gluing together the whole arrangement as they grow - and every colony has growth. The sunnyDs and the unnamed blue/metallic greens are competing with the hailanders as my fav zoas in the tank. Really pretty!

The Dead Sea of 2020 – long in case it helps someone else facing tank doom and recovery

I left the tank on autopilot for a relatively short trip of 7 days looking better than ever; look at that awesome growth especially on the two acroporas! I followed the same routine I have for the other 12 times this year that the tank has been abandoned for over a week – a 33% water change two days before and heavy feeding the day before - to make sure that nothing looked stressed and lipid reserves were high. I filled-up a reservoir that can last a month, and did not stress.

PreDOOM_above.thumb.jpg.36a9a34475d221473f3a5dee231283ad.jpg

Upon return as I approached my door, I smelled acropora mucus and then heard the jingle of the ATO alarm. This is what I saw:DOOM_above.thumb.jpg.a168478970c6f3910dc9f4481fbab172.jpg

About 40% of the water had been allowed to evaporate out exposing the two acros and the rainbow monti to 66.6 degree (ironic) air and the powerhead running dry but the aquaclear and heater miraculously still creating a trickle of warm water and oxygenation in the tank. Everything was covered in salt from the resulting waterfall. Which was good – imagine if all of it was somehow in the remaining water? As it was the salinity was at 55 ppt (1.040 SG) making the tank a nice experiment for testing coral tolerance and giving 2020 the chance to give me one last strong punch to the gut.

DOOM_back.thumb.jpg.91a0fb739f2ce44fc1f80b3b843f247a.jpg

I sat down. Cracked a beer and came up with a plan. Fortunately I had plenty of RO water on standby… I went super slow and added a cup of water every 15 minutes to refill the tank until the refractometer read 1.025@79. That took about 3 hours. It was brutal to leave coral continuously exposed, but the last thing I wanted was for the remaining corals to explode from a sudden shift in osmolarity. Indeed for the next couple days, pockets of tissue on each colony were swelling and exploding, but thankfully ONLY pockets.

I started doing a series of 33 - 40% water changes in combination with running floss (switched with every change as it filled with yucky) and carbon (switched every other day). I did one water change in the morning and one at night until greater than 95% of the tank volume has been switched – seven water changes thus far. I decided against a 100% water change because the LPS was pale but seemed alright and the zoas were sporadically opening, and I did not want to further stress anything else with a dramatic swing in nutrients or whatever else was going on in the doom-tank.

So where is it now? All of the exposed tissue (was probably days in chilly air) died, but there is still about 40% of the rainbow monti that is (hopefully) recovering. The yellow-tips is dead, minus one polyp that – who knows, may live (DOOM!). The staghorn has a ring of live tissue at its base, and is beginning to show polyp extension – so who knows, it may live and recolonize (DOOM!). The sunset monti hated the experiment and is 95% dead, but with a thin band of live tissue in the warzone closest to the rainbow – its prognosis is poor (DOOM!). The mystic sunset browned out, covered itself in mucus and lost tissue where the aquaclear was a waterfall on it – still it doesn’t appear to have polyp extension nor does it have massive tissue loss so it is being mystical. The stubbs monti is unperturbed – even the tips that were exposed. The melonberry is sorta gross with mucus but does not appear to be dead. The birds nest has plenty of recession low, but is starting to get fluffy again. All of the zoa colonies have some polyps fully open, and some in weird states so I have high hopes for recovery. All of the LPS and the FEEEEESCH ate and appear mostly unperturbed. The snails, cowrie and crabs are enjoying plenty of fine dining on mucus and slimy algae after they recovered from torpor as part of their 2020 year end stimulus package.

The good news is that its not ALL dead, and now we have a great benchmark for life at the start of 2021 – from the ashes.

Sorry about this disaster. This tank was looking fantastic. It'll bounce back......what substrate were you using?

Thanks for the well wishes! We use about 1 - 2 cm of crushed coral. I like having a semblance of a bottom substrate for critters to hide in and for a myriad of algae to persist in as well.

Things bounced back - shockingly fast! Ill take some pics and post a new reality FTS this evening, but it appears that The Doom ended up costing the tank only a single colony (the yellow-tip acro). There is still massive tissue loss on the rainbow and sunset, but they are both healing. The rainbow has been recolonizing old tissue like crazy and has probably regained about 10% of the lost surface, and the sunset has gone from perhaps 2% coverage to perhaps 6% coverage. The remaining "acro" (base has tissue, branch has none) has recovered about 20% of what it lost on the base but has not yet taken to the sky. All of the zoas have regained 95% of their color and the mystic sunset is slowly turning from brown to pretty again. In fact I am going to have to frag it again since it is starting to encroach on the glass and other colonies...

 

My biggest quandary is about the remaining acropora - should I remove the skeleton (snails doing fun gymnastics to keep it clean) or will the remaining tissue recovering around the base also recolonize the upright portion? Rather unsure about what direction to take... its ugly, but it may also result in a faster recovery for that colony as it would not have to recalcify the whole branching structure.

The extent of the tissue loss is very evident from the top down, but so is the road to recovery!

I am always amazed at how resilient coral can be when given the chance. The amount of recovery has been insane. That is not white band disease on the Rainbow Monti - it is rapid new growth! Interestingly, the flame red only stays at the outter rim of the colony and does not appear where it is rapidly re-colonizing old skeleton. I have decided the remaining acropora structure will stay. It is being colonized, although at a slower rate than the rainbow (likely because it experienced even more than 50% mortality).

 

I will never speak ill of the hardworking snails in this tank again (until I forget), they have proven to be gymnasts beyond what I would have expected in keeping new algae at bay. Tho perhaps that is a guilty concious because I am pretty sure they caused an overflow which caused the ATO to not run for a week...
