Betta Fish Companions: Best To Worst Ranked

The Siamese Fighting Fish also known as the Betta fish is the freshwater fish renowned for their stunning coloration, flowing fins, and spirited personalities. They come in vast array of colors ranging from vibrant reds, blues, purples and even metallic shades. Bettas are generally territorial, solitary and intelligent creatures who actively explore their territory, investigating new decorations and observing what’s happening outside the tank. They are not social creatures that needs ‘friends’ rather companionship for them is about peaceful co-existence. Bettas are curious, aware of their surroundings and often form a bond with their owners, often recognizing and interacting with them. Choosing companions requires careful planning as they see the entire aquarium as their domain and have big personalities.

An incredibly peaceful and timid fish who would actively avoid confrontation. Corydoras are strictly bottom dwellers, exploring through the sand or gravel at the very bottom of the tank searching for leftover food. They are good tank mate for betta as Betta fish lives and patrols the mid to top level in the tank and they remain at the bottom. Their paths rarely cross, giving each other space.

A unique and slender eel like fish, who also like corydoras, is a bottom dweller. Plus they are shy and nocturnal (active at night). During day time, they prefer to hide in caves or under decorations. They are good tank mates for betta as they remain at bottom and are active at night when betta rests, they will almost never interact or bother the betta.

A calm and peaceful schooling fish (swimming in group) who is gentle in nature and have a calm presence. They are mid level active swimmers. They are good tank mates for betta as their nature signals betta for a safe environment and won’t challenge betta. They remain at mid level leaving top level room for betta, plus they are more focused on each other rather then the betta.

Betta fish have genetically programmed aggression. They were selectively bred for fighting from centuries, similar to roosters being bred for cockfighting. This instinct cannot be trained out of them, so coexistence or friendship isn’t possible. When male betta sees another male, it’s instinct is to defend its territory by fighting with him to the death. The result would be severe injuries, stress, and the death of one or both fish. This is the worst possible pairing.

Tiger barbs are fast, energetic and semi-aggressive whereas a betta is a slow but graceful swimmer due to it’s long, flowing fins. These fins are an irresistable, slow moving target, tiger barbs can and would constantly nip it’s fins, shredding them apart which would leave open wounds, that are highly susceptible to deadly bacterial and fungal infections like fin rot. This physical torture causes stress for beta, weakens it’s immune system and would make its life miserable until it eventually gets sick and dies.

Betta with goldfish idea totally fails due to their total environmental incompatibility as bettas are tropical fish (needs warm water through a heater) while goldfish are cold water fish. They are polar opposites. Goldfish grows very large so much that it can stress out and injure the much smaller betta. Also goldfish are extremely messy and produces a lot of waste, which will quickly pollute the water and poison your betta.

Well choosing tank mates and caring for your betta fish is a must, as a pet's lifespan depends on the care it receives. Especially maintaining good water quality in the tank with a heater, proper diet and stimulating environment. Neglecting a pet's needs or state can lead to illness and shorter lifespan.
