Snakeheads

Snakeheads are air-breathing predators with real personality, from dwarf Channa that suit a species tank to giants that outgrow most homes. All of them jump, so a tight lid is not optional. Each profile lists adult size, tank size and temperament, since the gap between a dwarf and a monster is huge.
