Fish that can live with bettas need to be docile and non-aggressive to avoid conflicts, especially with male bettas who are known for territorial behavior. Here are some recommended tank mates for bettas:

• Corydoras Catfish: Chill bottom feeders that eat leftover food and prefer to live in groups of five or more.
• Tetras: Peaceful schooling fish like neon tetras and ember tetras, ideally in groups of six or more to avoid becoming nippy.
• Rasboras: Small, colorful, and peaceful shoaling fish (groups of 5-7) that stay under 4 inches.
• Ghost Shrimp: Transparent shrimp that scavenge for food and help keep the tank clean.
• Feeder Guppies: Short-finned and less colorful guppies that coexist peacefully with bettas.
• African Dwarf Frogs: Small and peaceful aquatic frogs suitable for 10-gallon tanks or larger.
• Clown Plecos: Small algae eaters with tough skin, good for tanks 15 gallons or more.
• Snails: Mystery snails and other peaceful snails are good non-fish companions.

Avoid fish that are aggressive, nip fins, or have long flowing fins that might provoke the betta. Also, male bettas should not be housed with other male bettas. Female bettas can sometimes be kept together in groups called sororities with experienced care. These companions generally thrive in community tanks with bettas if the tank is sufficiently large (typically 10 gallons or more) and has plenty of hiding spots and plants to reduce territorial stress. This advice comes from multiple sources about betta- compatible fish species and tank mates.
