Green plants will make their won food by taking in the carbon dioxide and then changing it chemically so that they are able to use it. Underwater plants do add a great deal of beauty to your aquarium. The plants will grow in the water to make a more natural surrounding for your fish. The fish can hide in the leaves of the plants and love to lay their eggs here. Also, a well planted aquarium is less likely to develop green water.
More fish die from overfeeding than from any other cause.
Your other pets may need to be fed everyday, but your fish do not. If you do feed them every day, uneaten food will accumulate in the tank. It will then blacken the sand a produce gases and other poisons that are harmful to you fish. Most fish can go a week without you feeding them because the will eat the microscopic plants and animals that naturally live in an aquarium. Fish should only be fed three times a week.
