Anyone know if stombus spp. broadcast fertilize or not? I saw two of my strombus (fighting conches) following each other around rather closely, and upon closer inspection, there appeared to be "another" appendage linking the two together. I read through Renee's (@Lionfish Lair ) clean up crew post and didnt see mention of eggs/viablity in aquarium, and oddly, I couldnt find much online about it either (no one cares about conches doing the naughty!), so I figured I would post up the few pictures I was able to get and see if anyone had the information I was looking for. The pair were right at the front glass, but the lights were ramping down, so the pictures are a bit difficult to see with clarity whats going on. Still, you can see the two linked by an appendage that is not an antenna, and retracted with a "puff" that dispersed into the water column quickly and tucked back up into the rear strombus' shell.
