If you want to keep guppies in a 20-gallon tank, the ideal number is around ten. Twelve is too many, especially for beginners. A general formula can be used to calculate the number of guppies that you should keep in a tank. Inexperienced hobbyists should keep their guppies to a smaller number than this. For example, two-inch guppies require two gallons of water, and a tank with 12 guppies is a bad idea.
Fish that can be kept with guppies
If you are trying to keep guppies in a tank, it’s probably best to avoid the Flowerhorn fish. They have a large, bulky body and a bright, yellow hump on their forehead. Flowerhorns are generally kept alone. They display aggressive behavior, such as nipping at other fish and fin nipping, during mating season. In addition, some large fish may mistake guppies for food.
Adding plants to the tank
Adding plants to your 20-gallon tank is one of the easiest ways to improve the environment for your fish. While clownfish are colorful and fun to watch, their bioload can overwhelm your fish’s biofiltration system. Adding plants to your aquarium will increase oxygenation, water quality, and stabilize the biological balance. Live plants are also beneficial to your fish because they divide space, reducing stress.
Avoid keeping aggressive fish with guppies
One way to avoid aggressive behavior in your guppies is to make sure that the tank’s water parameters are optimal. They like a temperature of 72 to 82 degrees Fahrenheit and a pH level of 7 to 7.5. Try to get treated water for guppies because they are sensitive to copper. Another important factor in choosing a tank for your guppies is its shape. They need to have a deep substrate to hide.
Adding a filter to the tank
Adding a filter to your 20-gallon aquarium is important if you want to get the most out of it. There are three types of filters: mechanical, chemical, and biological. Mechanical filtration strains debris, leftover food, and fish waste. Biological filtration uses beneficial bacteria that break down ammonia and nitrate to create a cleaner environment for your aquarium.
Stress on guppies
One of the most common problems with a guppy tank is that its water is not clear enough. You should add live plants to improve the tank water quality. Live plants are important for guppy tanks because they absorb toxins and nitrates from the water. Choose water plants such as Echinodorus Fancy Twists or Red Tiger Lotus. Other suitable plants include Rotala Rotundifolia or Rotala indica.
