Freshwater Fish Aquarium Basics

Freshwater fish are perhaps the easiest fish to care for in comparison to saltwater species because they are usually hardier. A basic aquarium set up will be required. You will need a tank, some rocks or substrate to line bottom of the tank. You will also need a filter, and some lighting.

When choosing fish, it is imperative to make sure the fish are compatible. Not only do they need to be compatible for water temperature and P.H., but they also should have similar food requirements. Try to keep the fish relatively the same size. It has been said that if a fish is small enough to fit in another fishes mouth, that is usually where it ends up. So don't be discouraged if this happens. Even fish that have been housed together for several months have been known to disappear on occasion.

You should feed freshwater fish twice a day. Use only a small amount of food, that the fish can consume within five minutes. Excess food will quickly become debris and make the tank dirty. The water in the tank must be regulated and tested weekly. Correct and discrepancies in water temperature and P.H. immediately to reduce stress to the fish.

Stress is significant because it causes illness in fish. It is important to monitor the activity and overall well being of the fish in an aquarium. The signs of stress will be fairly obvious. Slow moving or lethargic looking fish will require a stress coat that can be purchased at a local pet store. Try to avoid overcrowding the tank. This should help to reduce the amount of stress

Only change about one third of the aquarium's water at a time; this reduces any disturbance to the tank's inhabitants. Change this much water every two or three weeks, using either a bucket or siphon. When adding water, be sure to remove any loose or floating debris you spot. It is also crucial to make sure that the new water is close in temperature to the water already there, within two degrees or so.

The sides of the aquarium should be scrubbed regularly to remove an algae build up. Again be careful not to disturb the fish. Wash your hands thoroughly before and after handling the aquarium. Lastly, check the manufacturer's recommendation on filters and change them accordingly. Filters collect any fish waste or left over food. They can't function properly unless they are clean.

Introduce hardy fish to a new tank. These fish can withstand higher nitrite levels that are present in a new aquarium. Choose fish such as danios, barbs, gouramis, and live bearers. Don't add more than three to four small fish per week. Acclimation times vary per species, so check with your retailer before adding any other new fish.
