Betta fish diseases made suffers from a number of health conditions, but the good news to the keepers of this type of fish is that these health problems can be prevented and also treated. If the infections occur in the aquarium, they can be easily identified and treated effectively.
1. Fin and Tail Rot
As the name suggests, this disease affects the fins and tail of betta. It can be caused by bacteria or fungi. The fins and tail appear to melt away as a result of rotting.
It can be prevented by keeping the aquarium or living conditions of the fish clean.
Fin and Tail Rot can be treated by medications containing antibiotics, such as trimethoprim, erythromycin and sulfadimidine.
If it is effectively treated, the fatality is medium.
If you have had Fin and Tail Rot affecting your fish, you may have tried medications such as Tetracycline, Jungle Fungus Eliminator (JFE), Maracyn or Melafix. But the truth of the matter is that these medications are not quite effective in treating this infection, and some even kill your fish.
I have had little success with JFE and the other medications showed no success – they even worsened the condition. According to my own experience, the most effective medication for Fin and Tail Rot is Waterlife-Myxazin manufactured by a reputable company.
The medication is itself a 5-day treatment, and it comes with clear instructions on how to use it. The most amazing thing about this treatment is that it starts to give positive results from day one! According to the manufacturer, it can also deal with pop eye, body rot, raised veins, ulcers, ‘redness’, cloudy eyes and other health conditions.
If you have the Fin and Tail Rot disease or the related infections in your aquarium, I would encourage you to go for this medication. I have been using it since I discovered it in 2010 and I have had no disappointments with it.
Fin rot betta symptoms :
Depending on the severity of the infection, the signs may vary:
- Mild fin rot: slightly ragged fins, brownish fin edges
- Moderate fin rot: large fin disintegration, receding fin tips, black or red tattered edges, fuzzy growth on the fins
- Severe fin rot: Massive loss/chunks of fins missing, bloody fin bases, increased inflammation and redness, open sores on fins, body rot.
Fin rot betta causes :
- It’s usually caused by poor water quality.
- Common stressors such as overcrowding, higher bio load, and overfeeding/underfeeding can also weaken the fish’s immune system, thus making them susceptible to the disease.
- Fin rot can also develop as a symptom of a fungal infection or other illnesses.
Fin rot betta treatment :
- Maintaining clean water and ideal parameters can treat mild and moderate fin rot. Daily water changes are effective.
- For optimum results, add aquarium salt.
