We wouldn't dream of dipping a net into an aquarium and frying up the family pet for dinner. That's what Red Lobster is for. Home aquariums are for our personal entertainment and enjoyment. Aquariums add life and color to any room. They soothe sick patients at doctor's offices, and entertain small children while their parents are shopping at Nordstrom. The water should have a temperature in the middle to upper seventies and the pH should be neutral. This is usually the same set up and water balance you will use to house other fish as well, so it should not be a major concern when you add your catfish. Catfish are known to be somewhat goofy and comical, but this may depend on the species of catfish you have. Test the water daily and make any necessary adjustments immediately. Check the water for cloudiness and clean the filter regularly. Have you ever heard the saying that a happy baby is a healthy baby? Well, the same is true for fish. Fish should be made to feel as comfortable as possible in their new home. You can buy a timer from the pet store to make sure the light is on at the exact time each day. Otherwise the lighting could range from day to day and algae will form. Try to position the saltwater aquarium away from direct sunlight as this will also add to the growth of algae. The key to maintaining a healthy saltwater aquarium is to keep it clean and algae free. Aquarium kits can be purchased at places such as specialty aquatic pet stores, from huge retail chains, or again online. A fish lover can choose from small cylinder shaped tanks that can double as a coffee table lamp to wall huge wall sized aquariums. While, there are some basic things that will be included in most kits, such as, a filter, some substrate or coral and sometimes lighting, the kits themselves can vary greatly. These facilities have the resources to build large enough tanks to house the sharks. Sand sharks can be kept in a tank with other large fish. The sharks are usually fed three to four times a week to discourage them from eating tank mates. For the most part this works well, although, every so often some of the fish seem to disappear.
