What causes zoas to shrink? All of my hornets red/blue/purple, ked reds, tubs, etc. are shrinking in polyp size. Palys are all fine and large. They are about half the size that they were when I purchased them. Now the good news is they are adding polyps fairly quickly but the are smaller.
Tank is stable and all corals are doing well I just preferred the zoas when they were larger.
