What do you think? Would you call it "hard"?
I think it all has to do with dedication.
I would say its more of a commitment your making to care for and nurture your fish and corals, making sure they're fed and healthy, keeping their living space clean and inhabitable, making sure you tend to their every whim, and in the end it all pays off when you can kick back and enjoy your happy healthy tank.
