Common Koi Betta Fish Diseases

– Fin Rot: Fin rot is a bacterial infection that can damage the fins of your fish. Fin rot is quite common in koi betta fish and can be caused by several factors. Among the most common causes of fin rot in koi, and betta fish are poor water quality, water temperature extremes, poor diet, stress, and weakened immune systems. Fin rot can be identified by the development of a red or brown streak along the edges of the fish’s fins. It will often smell musty, and the infected fish will actively try to remove the damaged tissue.

– Dropsy: Dropsy is an infection that is most commonly seen in koi betta fish that are under stress. It can be caused by a variety of pathogens, including bacteria, fungi, and parasites. Dropsy is characterized by swelling in the fish’s abdominal region, caused by the build-up of liquid in the body. This can often be accompanied by the fish losing its appetite and being lethargic.

– Shell Disease: Shell disease is a common koi betta fish disease that is caused by a bacterial infection. It often appears as a gray or yellow spot on the fish’s scale and can spread rapidly if not treated. Shell disease is often caused by poor water quality or a low-quality diet.
