• D. Anaemia

Answer 1

The correct option is B Fin rot

Fin rot is a common disease caused by bacterial infection in aquaria and aquaculture due to poor water condition. Fin rot are caused by gram negative bacteria Aeromonas, Pseudomonas and Vibrio anguillarium. In case of fin rot, bacteria eats away the delicate membranes of fish. Fin rot starts at the edge of the fins, and destroys more and more tissue until it reaches the fin base. Hence, option B is correct.
