How many tetras can you fit with a male betta fish in ten-gallon tank?

While a 10-gallon tank is generally considered the minimum size for a betta fish, it's not large enough to comfortably house tetras. Tetras are schooling fish and need to be kept in groups of at least 6-8 individuals to thrive. A 10-gallon tank is too small to provide enough swimming space for a group of tetras, and the betta fish may become stressed or aggressive due to the lack of space.

Additionally, some species of tetras, such as neon tetras and cardinal tetras, are known to nip the fins of other fish, including bettas. This can lead to stress, injury, or even death for the betta fish.

If you're interested in keeping tetras, it's best to choose a larger tank, such as a 20-gallon tank or larger. This will provide enough space for the tetras to school and swim freely, reducing the risk of aggression from the betta fish.

Here are some possible stocking options for a 10-gallon tank:

* One betta fish with a group of 6-8 neon tetras or cardinal tetras

* One betta fish with a group of 6-8 rummy nose tetras

* One betta fish with a group of 6-8 ember tetras

* One betta fish with a group of 6-8 celestial pearl danios

* One betta fish with a group of 6-8 kuhli loaches

Note: It's always best to do thorough research on the specific species you're interested in keeping to ensure that they are suitable for your tank size and conditions.
