Is troll druid good at tanking in feral spec ? WoW?

Hey, i just made a troll druid level 7 and i want to know if they are good tankers because first of all they look really cool in bear mode and cat mode. Should i stick to him for tanking? I really like the neon colors in the druid and it makes it pop too ! So are they good at holding aggro and is that also a good race for them ? ty :D
