looks like the drawing below. i havent been able to get a good picture of it, it just looks like a rock attached entirely at the base to some live rock i have in my tank. 3 weeks after getting the rock it opened up! two parts slid out of it, one wide and shorter, i assume the intake, and the other a little longer and skinner by about half. they are red, and pretty, when you can see them. usually when the lights are on its only open a slit and you can see dark holes where both pump parts reside. when closed though, just looks like another piece of rock. any ideas? i will try to get a better picture but ive been at it forever said screw it ill draw one there isnt much to it lol. i do put those drops in your tank to feed it though.
