Beautiful!

Stylo has been closed up for a couple of days - no tissue loss, but confusing... all other SPS doing well. Had a small Alk swing (9-10.5 over 2 weeks) and large phosphate swing (0.01-0.2). Likely that the PO4 swing did this?

What's that bright yellow thing? Chalice?

Let me know what they say - would also be interesting in updating my sols.

Re. consistency - Than of Tidal gardens (coral farmer) used to grow with some natural light in a greenhouse - some of his corals would suffer from the winter-summer variances.

Sorry, I forgot about that part of the video when I posted it. Definitely tragic.

Wrasse seems to eating again! I just dosed the second round of prazi - Wrasse emerged, took a gross white poo and is acting much more "normal" - i.e. hunting the rockwork for pods and eating small amounts of frozen food. Maybe there's still some hope! Body condition is still quite poor.

I kept my QT tank in sunlight - the algae growing on the glass actually zero'd nutrients, which was nice in that QT scenario. I remember this 400 gal sunlight tank - Looks really nice and natural, but the corals look a little brown.

Melev's reef seems to have seen his tubastrea spawn:

You could do coral 18s rRNA sequencing for probably about $100-200 per pop, for just identification...

What's your PAR like with the xr15s?

Very nice! I've also done some work in wastewater epidemiology - underappreciated for sure!

Yep, mine were testing similarly when I lost mine unfortunately. It also took ~2 weeks to die.

Looks like there's actually a decent amount of ecotoxicological studies of polychaete worms (i.e. this one) Perhaps we can find an ecotoxin that doesn't harm aiptasia! So far, I've found copper and cisplatin as bristleworm killers, but neither are very practical for your purpose.

Prazi at a therapeutic fish treatment level didn't affect my bristleworms. I wonder whether a biological control might work - some anecdotal reports out there of arrow crabs eating bristleworms.

Definitely sad for the fish :(

Yep, not looking too hot... I've tried prazi, does not seem to have done anything. Regrettably planning to euthanize if things turn worse. It's stomach is very pinched, and it's swimming is a little disoriented.

Definitely a bummer :( How confident are you that the tank is fully cycled? Early on I lost a clown suddenly as well, and suspect it was due to incomplete cycling.

In my experience, fish often succumb to something else first, then get sucked onto the powerhead. If you're concerned about this though, you may want to put an anemone guard on the MP10 which will prevent small fish from getting sucked in.
