Kowloong or nine horn water dragon

the water pump in my fish tank went kaput after a year.i changed to a new waterfall type of pump with filter and it makes a horrible gurgling sound that gives me bad memories of a dying patient hooked to a respirator machine to help them to breathe.the gasp for air is audible in this new pump. the beshir or nine horn water dragon is a bully.i call him fei loong or fat dragon in honour of Samo Hung.Jackie Chan is xing loong.
