Zoanthid Eating Nudibranchs vs Salifert’s Flatworm Exit
I had initially set out to remove a large mass of flatworms that were on a colony of zoanthids, and placed 8 drops of Salifert’s Flatworm Exit (FWE) into 3 gallons of tank water in a bucket. After 10 minutes, I removed the zoanthids colony, and noted that all of the flatworms were dead at the bottom of the bucket. I also noticed, however, that there were a few zoanthids eating nudibranchs that were also at the bottom of the bucket, whether alive or dead it was hard to tell. Immediately I collected some nudis from a shipment of Solomon Zoanthids that was still acclimating and waiting to be dipped in iodine and freshwater, as usual.
The nudis were placed into two cups, a test group and a control group.
Test group
Control group
Each cup had 2 cups of tank water. Into one cup, there were added 4 drops of FWE, nothing was added into the control group.
In 30 seconds, one of the nudis in the test cup was falling from the side of the cup. In 45 seconds it looked like this.
In 60 seconds
The results were fast, effective, and much, much less stressful for the zoanthids colonies than the freshwater iodine dip. The control group showed no ill effects during this time. Obviously, the control group wasn’t going anywhere, so 4 drops were added since they were in better locations for pictures.
In 30 seconds stress sets in
In 45 seconds, lesions appear on the side of the nudi
In 60 seconds the lesion spreads
One of the nudi's appendages falls off at 80 seconds
90 seconds it’s falling to pieces
