How many guppy fish should be in a 20-gallon tank?

The number of guppy fish that can be kept in a 20-gallon tank depends on several factors, including the size of the fish, the filtration and aeration of the tank, and the frequency of water changes. As a general guideline, it's recommended to keep no more than 1 inch of fish per gallon of water in a freshwater aquarium.


Adult guppies typically grow to be around 1.5 to 2 inches in length, so a 20-gallon tank could comfortably accommodate around 10-12 adult guppies. However, if you plan to keep other fish or aquatic creatures in the tank, such as snails or shrimp, or if you want to provide more swimming space for your guppies, you may need to reduce the number of fish accordingly.


It's important to remember that overcrowding a tank can lead to poor water quality, increased stress and aggression among fish, and other health issues. So, it's always a good idea to learn about the needs of the fish you want to keep and make sure you give them the right environment for their health.



Can guppy fish live with snails in the aquarium?

Yes, guppy fish can live with snails in the same aquarium. In fact, snails can be beneficial to a freshwater aquarium as they help clean up algae and detritus and can also serve as a source of food for some fish species.


However, it's important to choose snails that are compatible with your guppies and won't harm them. The nerite snail, the mystery snail, and the ramshorn snail are all common snails that can live with guppies.


It's also important to keep an eye on the snails in the aquarium. They can reproduce quickly, so if you don't keep an eye on them, there could be too many of them.Also, some snails can spread quickly and hurt plants and other animals in an aquarium, so it's important to do research and choose snails carefully.


Overall, as long as the snails are compatible with your guppies and you take steps to maintain a healthy environment for all inhabitants, keeping snails in a guppie aquarium can be a great addition to the ecosystem.
