What fish can live with bettas: Understanding Betta Behavior
Before selecting tank mates for your betta, it’s essential to understand their behavior and temperament. Bettas are known for their territorial and sometimes aggressive nature, particularly among males. In the wild, bettas inhabit shallow waters in Southeast Asia, defending small territories against rivals. This instinct to protect their space carries over into aquariums, making it essential to choose compatible tank mates that won’t trigger their aggressive tendencies.
There are a few key traits to keep in mind when choosing fish to live with bettas:
- Territoriality: Bettas are territorial, especially in smaller tanks. They may become aggressive if they feel another fish is invading their space.
- Aggression toward flashy fish: Bettas may mistake fish with long, colorful fins (like guppies) for rivals and attack them. For this reason, it’s essential to avoid housing bettas with fish with similar physical traits.
- Calm temperament: What fish can live with bettas; While bettas can be aggressive, they are generally slow swimmers and prefer a quiet environment. Fast, nippy fish may stress them out or damage their delicate fins.

Factors to Consider When Selecting Tank Mates for Bettas
Choosing the suitable tank mates for your betta requires careful consideration of several factors. Not all fish are appropriate, and compatibility depends on multiple aspects, including tank size, water parameters, and the individual temperament of your betta.
- Tank Size
The size of your tank is one of the most crucial factors when housing bettas with other fish. A common mistake is keeping a betta with other fish in a small, cramped space. Bettas can survive in smaller tanks (though 5 gallons is considered the minimum), but for a community tank, you should aim for a tank that is at least 10 to 20 gallons in size. A larger tank provides more room for each fish to establish its territory and reduces the likelihood of conflict.
- Water Parameters
Bettas prefer warm water between 75°F and 80°F (24°C to 27°C). They thrive in slightly acidic to neutral water (pH 6.5–7.5). When choosing tank mates, it is essential to select species with similar water preferences. Avoid cold-water fish like goldfish, as they have different requirements and are incompatible with bettas regarding water temperature and quality.

The ideal tank mates for bettas are peaceful, non-aggressive species. Avoid fin-nipping species like tiger barbs or overly active fish that may cause stress for your betta. Fish with calm, docile temperaments are best suited for cohabitation.

Betta fish are particularly vulnerable to fin-nipping because of their long, flowing fins. Species known for fin-nipping, such as barbs or some tetras, should be avoided. Additionally, fish with flashy, colorful fins (like male guppies) may provoke aggression from your betta, as they can be mistaken for rival males.
