To keep the aquarium light on all night or not to keep the aquarium light on all night—that is the question: Whether 'tis nobler to give your fish a bit of darkness in the evenings, or risk stressing them out with a perpetually lit tank? Seriously, though, If there's one you don't want to do, it's stress out your fish. And fish do stress easily, especially if their environment has been altered drastically.

With the growing popularity and availability of fish like and decorations like our own line, “glow-in-the-dark” and fluorescent aquariums are becoming more and more common. Most of these animals and decorations are brightly colored in any light but under special lighting, the colors will really glow. There are two main kinds of light that are used in these aquariums: “blacklights” and actinic lights. Knowing the difference between these two can play an important role in making your tank really stand out, as well as in keeping it healthy.

Getting the proper amounts and types of lighting in your fish tank is vital to the health of your fish and plants. Even though your fish are in an aquarium inside your home, they still need to experience light as they would in nature so you want to be sure to provide around 12 hours of light a day. Consider using a timer so that you can consistently light the tank, inconsistent lighting may stress your fish which can lead to health problems.For a fish only tank, it is recommended that you have 3 watts of lighting for each gallon of water the tank holds. This ratio can be important when it comes to algae control and if you notice green algae taking over your tank it could be because your lights are too strong. You should plan to replace your lights every 8 months as the lighting will get weaker over time.Although most aquarium setups come with hoods that have lights fitted right into them, you can also purchase different types of to suit your needs. Most beginning aquarists need only to use the lighting that is provided with the aquarium as long as it is fluorescent lighting and your tank is for fresh water fish only.Aquarium lighting for tanks with plants is different than for all fish tanks. Aquarium plants can last as long as house plants if cared for properly. While you may be able to keep some fern like plants with regular fluorescent aquarium lighting, most plants require a full spectrum fluorescent bulb or tri-phosphor tubes which concentrate on the red, blue and green spectrum ranges.If you are planning on keeping plants in your fish tank, then the lighting requirements are a bit different. If you have tried to keep plants in your fish tank only to have them grow weak and die after a few weeks it is simply because you do not have the right type of light. Contrary to what many people think, aquarium plants are not hard to keep alive and should last as long as house plants with the proper lighting. If you want to keep anything other than a basic fern plant, you need a tri-phosphor tube or full spectrum fluorescent bulb which will provide the full spectrum of light that plants require.Keeping a fish tank can be a fun and relaxing hobby and with the proper lighting you can help keep your fish healthy and happy and feeling right at home in their tank.
