1 goldfish. It may seem tiny now, but they grow up to be around 6 inches. Add 10 gallons for each additional goldfish.
Example: 20 gallons + 2 more goldfish (10 gallons) = 40 gallons and 3 goldfish total.
you can put a betta in a 5 gallon tank
precisely 2.2
In that 150 gallon fish tank try to put fish and maintain it
The fish are not bad together. But way to many fish for a ten gallon tank. You put one fish for every gallon. They will probly do fine but you will have to clean more.
You can put it on a table if you choose. NEVER put a tank on the floor.
guppys are tropical fish. they require a heater, and 1 gallon is to small for a heater
you could put about 30,assuming they are all compatible
Yes.

It is generally recommended to have 1 inch of fish per gallon of water. So in a 186-gallon tank, you could have approximately 186 inches of fish. However, it's important to consider the specific needs and behaviors of the fish species you choose to ensure they have enough space to thrive.
A 1 gallon tank could have one betta fish, but you will need to be diligent about changing the water on a regular basis. The smallest tank that should be used, even for a betta, is a 2.5 gallon tank as it at least gives the fish swimming room.
Danios or glofish would be a good fish to put in the tank. They are schooling fish which means you would need at least three and I wouldn't put more than 5 in a ten gallon tank.
