1.I used keep a aquarium filled with some wonderful small fishes ( Goldfish, Goramins,Moly,Fighters,Neon), maintaining and feeding the fishes.Buying a larger aquarium by end of this week as old aquariums started leaking lately.
2.Maintaining three gardens (Two small, one nifty) along with my gardener's help ( Got tons of roses, guava, banana, mango trees).
3.Collecting my favourite Video Games
