ok this first one was sold to me as a PC rainbow... however every single PC rainbow that I have seen does not look at all like this one. They also don't look as colorful or as bright. anyone know what this is? This next one I got from an owner that did not know what it is but it is starting to show red coralites... the second picture is enhanced to show the red on the coralights. it would be nice to know what it is. anyone?
