Well we got a tank from my grandmother 8 years ago and it had little red dots stuck to the bottom she said it was algae...so my mother set the tank up and not long after they began to hatch (well 3 ) they was clownfish.....2 died quite early but one fought and we had him for 8 years with great success he passed on today! poor nemo! R.I.P he hatched the same year nemo was released.......
