<span style="color: black;"><span style="font-family: Verdana;">I purchased a Red Scooter Blenny and I'm fascinated by it. I was drawn to it colors, making it blend in with coraline until it moves. It does a lot of gliding and "walking" on its fins, as opposed to swimming, and when it gets upset the dorsal fin comes up and looks like a beautiful stained glass window. Is there anything special I need to know about it? How does one differentiate between a male and female? </span></span>
