I've got a neon dottyback who insists on moving sand from one corner of his tank to another; that's okay except that he spits most of it out during his journey and, unfortunately, it lands on several acans growing along his path. I carefully blow off the sand regularly and try to avoid stressing the corals thinking this might be sufficient; however today I noticed one acan that seems to have lost a polyp or two, possibly from the effect of sand buildup.
Anyone else had this happen? Don't think there is much I can do other than a radical reconfiguration of corals in the tank. All ideas welcomed.
BTW, water parameters are good and other corals are doing well.
