if they "melted" away, you may want to check for Nudibranch's. I had the same thing happen with my PPE's and AOG's, so I FW dipped them and found a Nudi. I got some Flatworm exit, and nuked them all....it is the greatest Zoa Nudi treatment!
Nudibranchs are not an issue is this case, but thanks for the tip.
Marvin, care to share any tips? Additives to the system they were in? Lighting? etc.
