Fish swim near the surface, often holding the dorsal fin above the water,
Skin became whitish in the area of dorsal fin and tail stem
The first symptom of the disease is pale skin color at the base of the dorsal fin and on the tail-stem. The infected fish will swim near the surface, often holding the dorsal fin above the water. The white spot gradually grows in size and the infected fish die.
This is an infectious disease, caused by Pseudomonas dermoalba. This is a rod-shaped bacterium with one or two flagella, usually 0.8 microns in length. It is transmitted by direct contact with infected fish or with objects taken from the contaminated tank.
How to cure:
An effective treatment is to give the infected fish a Levomycetin bath. The aquarium, gravel, plants, and decorations should be disinfected.
Any new fish should be kept in a quarantine tank before being introduced into the main aquarium. Plants, gravel, and decorations should be treated with a disinfectant.
