Hello, I just bought my fish tank 2 days ago I feed them very little in the morn. And very little at night... I use bottled water that they gave me at the store with the fish... yesterday morning the tank was cloudy I can't even see half of the fish only when they come to the front... what seemd to be the problem and what do I do to prevent it from happening again... thank you

Don't you need the water oxygenated ? Ask the fish store where you bought everything.

Hello,
Your new aquarium needs to cycle.
Every new tank must go through this process.
You can read about it here:
Aquarium Cycle / The Nitrogen Cycle

If you're still around, I can help you... just let me know.
