The answer is yes, and here is how. Guppies may not necessarily require lights for growth in the same way as plants. A decent light will be needed in order to create a behavioral rhythm for the guppies, and in order to get their colors really popping, and in order to get a good overall aquarium setup.<\/p>\n<p>In this guide, we will explore the reasons guppies\u00a0benefit from aquarium lights, as well as design a proper lighting cycle.<\/p>\n<h2><strong><b>Why Guppies Need Light<\/b><\/strong><\/h2>\n<p>In the wild, the guppy is subjected to predictable daily changes between day and night light levels. These daily cycles help the animal regulate activity, feeding times, rest periods, and mating cycles.<br \/>\nThese same light cycles would be beneficial to the guppy in captivity. Lighting can:<\/p>\n<ul>\n<li>Create a predictable, natural biological rhythm<\/li>\n<li>Promote active swimming and feeding<\/li>\n<li>Improve coloring and appearance<\/li>\n<li>Aid live plants in a planted aquarium<\/li>\n<li>Create an attractive display<\/li>\n<\/ul>\n<p>Without proper lighting cycles, guppies can become stressed and behave erratically.<\/p>\n<h2><strong><b>Can Guppies Survive Without Aquarium Lights?<\/b><\/strong><\/h2>\n<p>Theoretically yes. If the aquarium receives enough natural light from the room it&#8217;s in, or an adjacent window, your guppies may live without a separate aquarium light.<\/p>\n<p>But it&#8217;s one thing to live, another thing to be at your best, and without appropriate light, your guppies are the latter.<\/p>\n<ul>\n<li>Dull colors may be observed<\/li>\n<li>There may not be a predictable routine<\/li>\n<li>Live plants will do poorly<\/li>\n<li>You will have more trouble viewing your tank<\/li>\n<\/ul>\n<p>This is why even the most basic of guppy setups has an aquarium LED light.<\/p>\n<h2><strong><b>How Many Hours of Light Do Guppies Need?<\/b><\/strong><\/h2>\n<p>A normal guppy aquarium will need to be lit for 8-10 hours each day, which is about the length of time that the sun will usually shine for. The length that is provided by the light should be enough for a healthy aquarium, and will not cause the algae growth in the tank to become too much.<\/p>\n<p>A typical schedule might be:<\/p>\n<table>\n<tbody>\n<tr>\n<td width=\"260\"><strong><b>Time<\/b><\/strong><\/td>\n<td width=\"347\"><strong><b>\u0627\u0644\u0625\u0636\u0627\u0621\u0629<\/b><\/strong><\/td>\n<\/tr>\n<tr>\n<td width=\"260\">8:00 AM<\/td>\n<td width=\"347\">Lights On<\/td>\n<\/tr>\n<tr>\n<td width=\"260\">6:00 PM<\/td>\n<td width=\"347\">Lights Off<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n<p>&nbsp;<\/p>\n<p>Using a timer is highly recommended because consistency is more important than intensity.<\/p>\n<h2><strong><b>Can Guppies Sleep With the Lights On?<\/b><\/strong><\/h2>\n<p>No, similarly to most other fish, guppies need to have time without the light to get proper rest.<br \/>\nFish don&#8217;t exactly sleep the same way humans do, but during nighttime, guppies go through a rest period. At this time, they tend to:<\/p>\n<ul>\n<li>Swim less<\/li>\n<li>Stay near decorations or plants<\/li>\n<li>Respond slower<\/li>\n<li>Decrease their movement quite a lot<\/li>\n<\/ul>\n<p>It&#8217;s not good for them long-term to have their aquarium lights on all day, every day, as it can cause stress. It is generally best to provide about 8 hours of dark time per day.<\/p>\n<h2><strong><b>What Type of Light Is Best for Guppies?<\/b><\/strong><\/h2>\n<h3><strong><b>LED Aquarium Lights<\/b><\/strong><\/h3>\n<p>Today, LED lights for aquariums are the most common choice for a guppy tank.<br \/>\nSome advantages of LED lights include:<\/p>\n<ul>\n<li>Energy efficient<\/li>\n<li>Produce little heat<\/li>\n<li>Last a long time<\/li>\n<li>Variable light intensity<\/li>\n<li>Bring out the coloration of the fish<\/li>\n<\/ul>\n<p>Generally, a <a href=\"https:\/\/seaoura.com\/collections\/aquarium-light\" rel=\"nofollow noopener\" target=\"_blank\"><u>full-spectrum LED light<\/u><\/a>\u00a0 will provide the most natural look and bring out the red, blue, yellow, and orange coloration of the guppy fish.<\/p>\n<h3><strong><b>Natural Sunlight<\/b><\/strong><\/h3>\n<p>Certain hobbyists choose to position tanks by windows in an attempt to take advantage of natural light.<br \/>\nThough this may sometimes work, direct sunlight can lead to:<\/p>\n<ul>\n<li>Algae blooms<\/li>\n<li>Fluctuations in water temperature<\/li>\n<li>Overheating<\/li>\n<\/ul>\n<p>Safe light comes from indirect room lighting, rather than from directly facing the sun.<\/p>\n<h2><strong><b>Do Guppies Prefer Bright or Dim Lighting?<\/b><\/strong><\/h2>\n<p>Guppies do well in average light conditions.<br \/>\nReally bright lighting can cause guppies to look a little worried in a bare aquarium.<br \/>\nTo make your guppies feel safe, include some of the following in their aquarium:<\/p>\n<ul>\n<li>Live plants<\/li>\n<li>Floating plants<\/li>\n<li>Driftwood<\/li>\n<li>caves<\/li>\n<\/ul>\n<p>These all create shadowy regions where your guppies can swim if they feel nervous.<\/p>\n<h2><strong><b>Lighting Considerations for Planted Guppy Tanks<\/b><\/strong><\/h2>\n<p>Most guppy keepers also keep live plants.
