About 3 weeks ago, I received an octofrogspawn from WWC. It seemed to be doing fine until a couple days ago, I noticed a few small polyps that had dropped. However, only very young polyps are the ones that seem to fall off, not the large established ones. I have only seen like 3 tiny single polyps that have fallen. Any idea what is going on? My water parameters are: Nitrates, Phosphates, Nitrites, Ammonia, all undetectable. Calcium at 440. Salinity at 1.026.
