The most important need that any creature has is the need for food. This is not different for fish. It is important to mimic the type of food that a fish would typically eat in the ocean. These foods can be purchased in flake, tablet, or frozen forms. In addition, there are vitamins that can be added to the foods to replace any nutrients that may have been lost in the freezing or drying processes. The first thing you should be aware of is that you will need to buy filtered water or buy a reverse osmosis kit. Otherwise you can use regular water, making sure it is at the correct temperature, and add in chemicals to remove chlorine and other unwanted chemicals. Maintenance is a necessity and you will need to clean your tank at least once a month. However, if you notice a significant amount or a large population of these worms, you will have to take action as they could cause death. Coral is a wonderful addition to any aquarium. Many people are uninformed as to how to care for this animal. It is advised that you learn all you can about the animal, how it functions and lives before adding it to the aquarium. H and water temperatures have been established. Now it is time to purchase the fish! Buy hardy fish such as danios, barb, gouramis, and live bearers. They should be able to withstand the high nitrite levels and ammonia in the new aquarium. Only introduce about four fish at a time. Float the fish in the bag in the aquarium for about fifteen minutes before adding them to the tank. There are things that should be done daily to care for fish and some things that need only be done weekly or bi-weekly. Daily maintenance of an aquarium is fairly minimal. Look at the fish every day to make sure they appear to be overall healthy and happy. This may seem silly, but the main cause of sickness in fish is stress. 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. It really doesn't matter where you buy your starter kit, but keep in mind that it is extremely important to buy your fish from a reputable dealer.
