Cant believe I did that.
Added sand to my tank yesterday. May get a pic today. My Rainford goby is happy. He does not have to sift the detritus build up anymore.
Cant say Mrs. clown is similary pleased. Even though I left their area in front of their house and baby making area clean, she is still determined to move it all around. Mind you, she has basically only seen a bare bottom in "her" tank, most of her nearly 8yrs.
Now, I need stupid sand clean up creatures. Hmmmm!!
