Oh the ''neon'' damsel .
I have never actually seen one other than pics .
I had salt in the late 70s early 80s when UG filters were the norm ,wet/drys were starting to come out and the only protein skimmers were archaic air driven compared to now thus reef tanks weren't the norm , lol plus lighting was just fluorescent tubes .
We did collect rock and lots livestock right from reefs because regulations weren't put in place till early 80s .
Rocks would come with tiny octopus , tiny morays and mantis and bristle worms .
