Can you put 3 platy zebra danios and 2 fantail guppys in a 5 gallon tank?

It is not recommended to keep 3 platy zebra danios and 2 fantail guppies in a 5-gallon tank. While platy zebra danios and fantail guppies are relatively small fish, they both require a minimum of 10 gallons of water each. In a 5-gallon tank, the fish will be overcrowded and stressed, which can lead to health problems. Additionally, the tank will be difficult to maintain, as the water quality will deteriorate quickly with so many fish in such a small space.

If you are interested in keeping platy zebra danios and fantail guppies, you should consider getting a larger tank. A 10-gallon tank would be the minimum size for these fish, but a 20-gallon tank would be even better. This will give the fish more room to swim and explore, and it will be easier to maintain the water quality.
