They are peaceful fish that like to be kept in groups. They are good and active swimmers and pretty much move around all the time. Sometimes you will see the males chasing the females trying to impress them by wiggling their fins.

If you notice that your fish is constantly hiding, it could be an indication that they are stressed or ill.

The Tank Requirements of Guppy

They are native to the warm freshwater of South America. You can keep them in a 5-gallon tank but most people choose a 10-gallon tank to keep Guppies. They are warm water fish so you have to use a heater to warm the water.

Keep the temperature between 75oF-82oF. Place your heater at one end of the tank, and a thermometer at the other end to check that the water is heated through consistently. The ideal pH is 7.0-7.2

A hang-on back filter will be fine for most setups. For a larger tank (bigger than 50 gallons) you might want to consider using an external canister filter.

Plant plenty of live plants. Use rocks and substrate. You can plant Hornwort and Amazon Sword Plants. Guppies spend the majority of their time in the middle or top section of the tank.

Diet of Guppy

They are omnivores which means they will eat both plants/vegetables and meats. Their main diet should be quality fish flakes. Make sure to choose a product that is high protein and not filler foods.

You should them once or twice a day, and only an amount of food which they can eat within 2 minutes. Do not leave leftovers in your tank. This will break your tank water chemistry.
