I know I know my pictures are terrible. So I was looking at my tank just now and noticed what looks like a limpet or a snail with no shell spewing white liquid in bursts into the water every 5 seconds. This went on for a good 45 seconds. Any one know what is is and if it is jizzing in the water? I tried to film it real quick but its a little tough to make out. I need to upgrade my iphone 4 lol. Here is a video and then below is a picture a little closer up. Its just under the rock overhang.
