If food is accumulating in the tank and the filter, it's a sign that you're providing too much food. Also, if red or black algae are growing on the glass surface of the aquarium within a week of cleaning, it's another sign that you're overfeeding [source: Aquarium Pros].
I prefer to perform a 30% water change on my aquariums when it is time. Larger water changes seem like they would be better, however, you can bring on a lot of stress to fish and plants with drastic water changes. The goal of changing water is to keep the fish healthy.
Some fish swim continuously, others stay in one place. Deviation from that norm usually indicates stress.

Some people say once a week, while others say once a month. The real answer is that it totally depends! Several factors include the size of your tank, how many fish you keep, and how much biological filtration (e.g., beneficial bacteria and live plants) you have.
No, you do not need to feed most adult fish every day. While it depends on the species and age, healthy adult fish in a community tank generally thrive on being fed once a day or even just a few times a week. Overfeeding often does more harm than underfeeding by polluting the water.

Ultra-low phosphate, high-porosity carbon, recommended at 1 tablespoon per 7.5 gallons for marine environments. Standard aquarium-grade activated carbon, recommended at 1 tablespoon per 3 gallons, versatile for both reef and freshwater systems.
The easiest freshwater fish to keep alive are Betta fish, Guppies, Platies, and White Cloud Mountain Minnows. These species are highly resilient, adapt well to basic water conditions, and are less prone to common diseases, making them perfect for beginners.
Here are a few of the most common problems that beginning aquarists experience.
Water changes clear the water temporarily, but in a day or two the cloudiness reappears, often even worse than before. That's because new water provides a fresh supply of nutrients, causing the cloudy water bacteria to populate even more.
On average, the typical aquarium fish poops somewhere between once daily and every few days, though high-metabolism fish like goldfish may defecate significantly more often. How often a fish defecates depends on numerous factors, including size and metabolism.
