Dying Lithophyllon Coral Rehabilitation

A local fish store (LFS) called me to ask if I wanted to try to save some of their corals. An employee had overdosed their reef tanks with a chemical used to treat flatworms (I was not told what chemical it was). When I arrived, honestly, I was shocked at how bad many of the corals were. I don’t know if these corals were dying from an overdose of some unknown chemical or if the flatworm toxins were killing them. Either way, something was poisoning these corals to death. I picked up two “chalice” corals, amongst others. These dying Lithophyllon coral mouths were gaping open, the tissue was falling off, and what tissue did remain was barely hanging on. Rehabilitation was going to be dicey. (Photo of Litho#1 taken 11 May 2013)

Dying Lithophyllon Coral Inspection and Dipping:

When I brought them home, I temperature acclimated them to my quarantine tank and prepared the dips. Like most of my rescues, I dipped the corals for pests. (Photo of Litho#2 taken 11 May 2013)

*NOTE: This post tracks the corals as “Litho#1” and “Litho#2” to show individual progress.

Coral Quarantine:

After the dips, I placed the two dying Lithophyllon corals into my quarantine tank in a low light, low flow area. I made sure that no crabs would bother the coral, especially with all the decaying tissue. Since the corals were poisoned, I made sure the quarantine tank had new carbon to help absorb anything that the corals might leach. Both corals did start to quickly recede, so I tried to stop it by smearing a bead of superglue gel along the receding edge (white lumpy band in the photos below). Rehabilitation was definitely already proving rough. (Photo of Litho#1 taken 11 May 2013)

The corals also refused to eat until about a month after I received them. I started them on fish food pellets (shown here and above) since they are quite processed. In my experience, sick corals seem to digest fish pellets better than whole foods (like mysis, etc.) This helps them recover faster. (Photo of Litho#2 taken 9 June 2013)

Coral Grow-Out:

After stopping the recession with superglue and maintaining regular feedings, the corals started to heal quickly. And how great they started looking! After 30 days in quarantine, I inspected, re-dipped, and placed them into the grow-out tank. (Photo of Litho#2 taken 4 August 2013).

A month later (8 December 2013), Litho#2 was growing down its skeleton.

Nearly a year later, both previously dying Lithophyllon corals were growing rapidly. This Litho#2 is shown on 1 May 2014, when it was fully rehabilitated. Below is a close-up shot showing the corals’ beautiful patterns.

Conclusion:

I had very little hope for these dying Lithophyllon corals due to their poisoned state. However, the fast reaction of the LFS along with continued care over a year fully rehabilitated these two corals. Shown below are the before/after photos of the dying Lithophyllon coral rehabilitation. One coral was nearly immediately rehomed, and the other coral was rehomed a couple years later.
