is it alive still? i thought they go in the sand usually?
i also have one on this large flat piece of rock in the front of it so i use this as my cave rock =) i love it like fish will swim inside it cuz its like open a little (or was till my mom was scrubbing that rock to put in my 125.. anyone know of any glue or putty i can use to put the top half back on?)
but ya i think they look cool
