Morning All: I have two leather cup corals that I got 10 days ago. One is about 1" diameter and 4 inches tall the other is 2" diameter and 6" tall. Both are laying on their side. Should these be standing up? The larger one looks like it's making some attempt at sitting up right but still has a ways to go. The smaller has showed no sign of trying to sit upright. Do I need to be worried about this??
