FAQ:
Q: How much fish can you put in a 3 gallon tank?
A: Following the “1 inch of fish per gallon of water” rule of thumb, you can put three 1-inch fish in a 3-gallon tank. You can also keep invertebrate tank mates with one 2-inch fish, like a betta . You can unknowingly overstock a 3-gallon tank even if you bring home just one pet fish.
Q: What kind of fish can go in a three gallon tank?
A: Therefore, the best fish options for 3 gallon freshwater aquariums are a single male betta fish, or groups of dwarf fish such as Ember Tetra or Dario Dario. Because of the betta’s territorial nature, these aquariums make ideal betta homes.
Q: Can I put any fish in a 3 gallon tank?
A: After cycling the tank, you’ll have to decide what fish to get, of course. For a 3.5 gallon, the best option for me would probably be a betta. These look well on their own. Aside from bettas, you can put any live bearing fish, such as guppies, or a shrimp.
Q: How many guppies can live in a 3 gallon tank?
A: Technically, you can keep 2 guppies in a 3-gallon tank. The thing is that despite this, these guppies will not have enough room to swim freely. This may cause them to become sick. The water quality and chemistry may also be compromised and this may affect the guppies.
