Why does this happen and how do I prevent it?
Disease causing bacteria and fungus are present in every aquarium environment (although specific species may be introduced with new fish) but will rarely cause a problem with good water quality and happy healthy fish.
Avoiding stress and keeping good water quality in the tank is key to avoiding and treating fish infections. Test your water for abnormalities in ammonia, nitrate, nitrite, pH and correct if necessary.
Using Aquilibrium salt with treatment will help the fish recover as it makes the natural processes fish use to stay alive far easier to manage.
Key areas to consider and regularly monitor to prevent outbreaks and aid recovery:
- complete regular maintenance
- regularly test water for abnormalities
- consider a quarantine before introducing new fish to an established tank
Ulcers can occur as a secondary infection as a result of severe parasite infestation so look out for symptoms of parasites and treat accordingly.
Symptoms of internal infections can also be a sign of viral infection.
You can not treat viral infections so can only support the fish by supplying optimum water quality, aeration and Aquilibrium to allow their immune systems to combat the virus.
