Can a Betta Fish be put into 10-gallon tank with other fish?

While a 10-gallon tank is a suitable size for a betta fish on its own, it also depends on the compatibility of the other fish you intend to keep with the betta. Bettas are known for their territorial behavior, so it's crucial to select tankmates that are peaceful and non-aggressive.

Here are some factors to consider when choosing tankmates for a betta fish in a 10-gallon tank:

1. Compatibility: Bettas should not be housed with fish that are overly active, fin-nippers, or aggressive. Avoid species like larger barbs, certain tetras (like tiger barbs or nippy fin tetras), and cichlids.

2. Temperament: Look for calm and peaceful fish that won't bother the betta. Good options include:

- Neon tetras

- Zebra danios

- Rummy nose tetras

- Ember tetras

- Cardinal tetras

3. Size: Choose fish that are relatively small and won't outgrow the 10-gallon tank. Avoid larger fish that may intimidate or stress the betta.

4. Water Conditions: Ensure that the tankmates you select have similar water preferences as the betta, including water temperature, pH, and hardness.

It's essential to research and carefully select tankmates that are suitable for a betta in a 10-gallon tank to create a harmonious and peaceful environment. If you're unsure about specific fish species, consult with experienced aquarists or research reputable sources before making a decision.
