With the 2, they buddied up, would grab a mouthful, ascend to the top of the tank and sift the sand out on the way up, covering everything... since I caught the one, the one still in there stays at the bottom, and the problem is eliminated. I mistook this for a jawfish, so if I decide to get a jawfish instead in the next 2 weeks, Im going to catch this guy and give it away also. Its too cheap of a fish to ship (meaning it would cost more to ship than it would to buy it locally, or on here for 9.99).... but if I do give it away locally, its spoken for.
