So I was walking by my tank this evening with the night leds on and I saw a somewhat big blob floating through my tank. Upon closer inspection my scooter blennys were swimming around attached to each other side by side. They would do this for about 20-30 seconds, then drop and start again. Is this their mating dance? They are both still fairly small (about 3 inches each), so I wasn't sure if they were mature enough to start this. I tried to get a video, but I wasn't able to put any lights on without them scattering.
