You have to get lots of things for your aquarium, and all a variety. If you're broke, just stock up on the cheap-o aquarium decorations, a background, mix up some arrow fish, cuttlefish, and goldfish, (they're the cheapest) and follow the steps below. If you can afford 30-40k for a fish, add a wide variety like mine, some kelp and coral, an air bubbly, a statue or fountain, a background, and here are the steps to follow.
1. Keep temperature on hot 2. Feed once or more DAILY. 3. Change music occasionally. Once a week, maybe. Fish like a change! 4. Feed tank every time you put in a new fish.
Follow these simple steps and your tank will go up a half a % to 3% daily. smile
