Orange reddish in color. Found on the backside of the rock so no lights could get to them and in overflow. They are soft to touch, no body shell, and 1 orphice. Not sure what they are??

do they move or no at all?
If they are attached to and don't move it is sponge. If they shrink a bit after you touch them can be tunicate (from the photos can't see do they have 2 tube openings on them)

Tunicates which are reef safe filter feeders

if you see openings (2 in your case) sound like tunicates. But if they are, when you touch them they have to shrink a bit and usually the openings are closing)
If they don't shrink at all, then they are sponges (if the openings are at random places)
