Why Does My Betta Have A Curved Back?


Immunity is a vital factor not only in human bodies but also in fish. Poor immune systems would trigger tuberculosis for your betta fish, which eventually results in a curved spine.

Betta fish might evolve a bad immune system if they have a strain. Thus, raising your betta with greatly compatible tank mates is essential. Any incompatible companions would let betta fish stay under a lot of stress, leading to its poor immunity. This would eventually make its spine more bent.

Hence, attempt to avoid factors that would worsen your fish’s immunity and nourish them correctly with adequate food.

Water Standards

Keeping the proper water standard is crucial for betta fish. If the water quality is not clean, you could witness your pet suffering from tuberculosis. In addition, the water standard might depreciate when you keep various kinds of fish.
