i notice that my siamese fighting fish always stay at the bottom and dwell among a particular wood with plants.its sort of its territory.but i believe that bettas are top surface dwellers but these guy does not go up and even have his food. but strangly i notice one bahavior 2day as there was a dead tetra in the tank, and he sort of guard the dead and prevent other fish from having it. and he then carefully dragged to a plant to the top and hid it there and consumed it....maybe he's a scavenger type.anyone experience this with thier siamese.
