sand or stone gravels?

  • We are currently upgrading MFK. thanks! -neo
Oh no, what happened?
 
OK, I remember that now. :(
 
well, I've just finished adding black sands in the tank, hopefully my mbu will enjoy it.
 
Sorry off topic, but Mbu's don't bury themselves like fahaka's?

I use sand for my fahaka :)

EDIT: Nvm just saw the video.
