Acropora Rehabilitation Before and After

Back in 2012, I took in several corals from a fellow reefkeeper, knowing they were all rescues. Included in the bulk were a few dying Acropora corals that desperately needed rehabilitation. However, rehabilitating small polyp stony (SPS) corals has its own challenges, and in many cases, these sensitive corals may experience a more rapid death than their large polyp stony (LPS) counterparts. Below I will cover the initial inspection, diagnosis, treatment, for a complete dying Acropora coral rehabilitation.

Assessing Dying Coral Health:

All dying Acropora coral were brown, not extending polyps, and had white marks on them. Upon initial inspection (and not shockingly), they had red bugs (Tegastes acroporanus) and Acropora-eating flatworms (AEFW). I treated the AEFW and red bugs with a series of coral dips as part of rehabilitation efforts. I also inadvertently subjected the tank to a reduced temperature (thanks power outage), which quite possibly killed the red bugs. (At the time, Interceptor was the normal protocol for treating red bugs, but there were also several other suitable treatments.)

Since AEFW lay eggs, it was critical to regularly inspect the coral and re-treat to completely eliminate the parasites. Thankfully, red bugs are live-bearers, so once they were initially eliminated, I no longer had to worry about them.

Quarantined Acropora Coral:

Of course, Acroporas require stable salinity, alkalinity, magnesium, calcium, etc. Given that I had over 50 corals undergoing rehabilitation at the time, my quarantine tank was not exactly a healthy aquarium. I had to focus particularly hard to make sure the other dying corals did not adversely affect the SPS. Water changes to remove excess nutrients were crucial. Once the Acropora parasites were gone, I maintained my alkalinity at 9 dKH, magnesium at 1350, and calcium at 450. I also performed 20% weekly water changes.

Previously Dying Acropora Coral Rehabilitated:

With stable parameters and a lack of parasites, this previously dying Acropora coral was quickly rehabilitated. They can heal quickly and add a beautiful touch to the aquarium. However, I don’t recommend Acropora rescues for beginners as they can have more severe pests than LPS corals, are sensitive to poor water conditions, and require careful monitoring of water parameters.

Dying Echinophyllia Coral Rehabilitation

A friend of mine asked about this dying Echinophyllia coral’s rehabilitation, “How did you even know there was any living tissue on that one?” That’s a really great question, because this Echinophyllia sp. (also known as a “chalice”) coral was in a really bad shape and dying.

There was a local fish store (LFS) near me back in the day that used to have massive coral runways with massive runway sumps below. If any corals died, the employees would just throw the pieces into the sump. I used to take a UV-light and run it along their sump to see if there was anything with the tiniest hint of life clinging to it. Although I didn’t get this particular coral there, a UV pen was what gave me hope. This coral might be brown under regular light, but it fluoresced a beautiful green under UV.

This dying Echinophyllia coral got its start with me on 22 May 2012. Of course, I dipped it to check for parasites and placed it in a low light, higher flow area.

Coral Quarantine:

Just a little over a week later, on 3 June 2012, the transformation was amazing. With regular target feedings, this previously dying Echinophyllia sp. coral was no longer clinging to its skeleton, showed off its orange mouth, and it developed what can only be described as “glitter” throughout its tissue (notice the specks around the mouth). I was getting excited! Its rehabilitation was coming along!

By the end of June (30 June 2012), just a little over a month later, and the Echinophyllia sp. coral had nicely filled out. It was time to transfer the coral from quarantine to the grow-out tank, so it was dipped again and inspected to ensure it was clean.

Coral Grow-out:

This photo was taken on 14 August 2012. The grow-out tank’s lights were much stronger, so this coral started out in the sand again. Even down in the sand, the coral began to develop some beautiful coloration, with blues, greens, and orange mouths.

Fully Rehabilitated:

By 19 February 2013, the coral looked as if it had been beautiful all along. There were no signs of fragging, and the coloration was fantastic. This previously dying Echinophyllia coral was rehabilitated!

After about a year-and-a-half recovery (2 November 2013), the coral was ready for a permanent home (excuse the oversaturated photo!) This coral went from essentially the “trash bin” to having a new start.
