There are none the would thrive in such a small container. Two and a half gallons is the minimum for even a Betta, with five gallons being even easier to maintain.
If you MUST keep a fish in a one gallon container, a toy or similar fake fish is best.
guppys are tropical fish. they require a heater, and 1 gallon is to small for a heater
You can safely keep a shoal of neon tetras (tropical) in a 17 gallon tank
length and width for a 55 gallon fish tank
How about a beta? They are solitary fish, but they do well in small tanks. A five gallon tank would be more than enough for one. Anything less than 1 gallon is not enough.
The tank you have described is extremely small and should not be used to house any fish. 1 gallon is not enough space for a fish to swim around, and it will most likely have a very short life if kept in this tank
For a 5-gallon fish tank, you will need a filter, heater (if keeping tropical fish), thermometer, water conditioner, substrate, decorations, fish food, and a water testing kit to monitor water quality. It is important to properly cycle the tank before adding fish to establish a healthy environment for them.
71 liters is almost 19 gallons and the rule with tropical fish is one inch of fish per a gallon of water at there adult size so it would be different for every fish you got like if the fish adult size is 2 inches that you could have about 10 of that fish in your tank.
probably a 50 gallon tank would be best.
half tea spoon every gallon water
you can put a betta in a 5 gallon tank
U buy tropical fish and get a background and then that is how u can do that
You can fit a 5 gallon fish tank on a school going desk.
