My xenia have shrunk from about six inches to only one inch. They are usually pulsing like crazy but right know none of them are pulsing. Also they are usually a beigh color but now they are almost white. Do you think something is wrong with them. I put in new lights last week ( power compacts 8 55 watt bulbs). Power compacts dont require a break in period do they? Do you think my xenia are sick?
