What fish does good with betas?

It's tricky to find fish that do well with bettas. Bettas are known for being aggressive, particularly towards other males. While there are a few peaceful fish that can sometimes be kept with bettas, it's always best to err on the side of caution.

Here are some general guidelines and potential candidates:

General Guidelines:

* Larger tank: A larger tank (at least 5 gallons, ideally more) provides more space for the betta to feel less threatened and for other fish to avoid it.

* Plenty of hiding places: Caves, plants, and other decorations offer refuge for less aggressive tankmates.

* Compatibility: Always research the specific needs and temperament of the fish you are considering.

* Observation: Carefully observe the behavior of your betta and tankmates. Any signs of aggression should be addressed immediately by separating the fish.

Potential Tankmates:

* Small, peaceful fish: Consider tiny tetras like neon tetras, ghost shrimp, snails, and some dwarf shrimp species. These can be peaceful and stay out of the betta's way.

* Fast-moving fish: Some fish that are fast and agile, like harlequin rasboras or certain danios, might be able to evade a betta's attacks.

* Similar size: Consider fish that are around the same size as your betta, as this can deter aggression.

Fish to avoid:

* Other male bettas: Never keep two male bettas together.

* Similar species: Male bettas are known to attack other male bettas, even those of different species.

* Fin-nippers: Fish known to nip at fins, such as certain barbs, are a bad choice.

* Aggressive fish: Avoid any fish known for being territorial or aggressive, like cichlids.

Remember:

* Every betta has a different personality. Some may be more peaceful than others.

* It's always best to err on the side of caution. You are better off keeping your betta solo or with a select few compatible tankmates.

* Constant monitoring is crucial. If you notice any aggression, you must separate the fish.

It's highly recommended to consult with experienced aquarists or your local fish store for more specific advice based on your betta's individual personality and your tank setup.
