Red bellied piranha :z

Emegency blip today, one of my six red bellied piranha. Very boring fish to keep, even at feeding times, depending on their moods and how shy they are ?
Most people think they're a dangerous animal to keep in the aquarium at home but mine being more scared of me than I am of them, makes them unpredictable rather than a danger.
Fed regularly on mussels, white fish pieces, pig and ox heart and the occasional scattering of high protein fish pellets to keep them in good health and body colour.
