Quick question for the R2R community. If all goes right I'll be picking up a pictillis anthias trio in 4 weeks, though I have a pretty persistent coral-eating pest that only comes out at night and was wondering if pictillis anthias will be active at the same time? They're slightly smaller than regular amphipods so size won't be a problem. They'll be one of the only fish if not the only fish in my 9 month old 120 gallon tank. Thanks!
