Fin rot is a betta bacterial infection of the fins that virtually eats away at them. At first glance, a fish's fins or mouth may look damaged. This could have been the first problem that led to infection. Fins, mouths, and tails, on the other hand, degrade and rot away with time.
Fin rot is caused by bacterial infections caused by the likes of Pseudomonas fluorescens, which causes ragged fins and fungal infections, which cause white fluff. Generally, fin rot is caused by bad water quality resulting in a weakened immune system, causing the fish to be much more susceptible to a bacterial or fungal infection.
M. marinum-induced tuberculosis in adult zebra fish; most of zebrafish died within 2 weeks of infection with 8970 bacteria, while infection with 5 CFU caused 44% mortality and infection with 60 CFU caused 83% mortality by 16 weeks. The infected fish showed a reduction in feed intake and weakened swimming for 1 week during the period prior to death.
Dropsy, characterized by visible swelling and protruding scales, is a symptom of a deteriorating health condition in your betta fish and is relatively easy to diagnose. However, determining the underlying cause of Dropsy can be more challenging. The primary cause of Dropsy is usually attributed to bacterial infection.
Infections. Bacterial or viral infections can also cause Bettas to develop swim bladder disease. This is obviously very concerning, because aside from swim bladder disease, infections can cause a whole host of other problems for Bettas. Bacterial infections are the most common type of infection that leads to swim bladder disease.
