Kui kala veel elus siis wikipedias kah artikkel selle kohta ja eks võid ju proovida ravida, aga ega ma ise mingi spetsialist pole... ehk eelpool mainitud on tõsi, et ellu ei jää. Kui inglise keelt oskad siis ravi oleks midagi nii (kui sa juba wikipedias ringi ei uurinud) -
http://en.wikipedia.org/wiki/Fish_Dropsy) :
Dropsy is not very contagious; however, if a fish is diagnosed with dropsy, it is important to remove it from the aquarium because the infected fish will contaminate the separate water and end up dying. If there are multiple fish, treat the afflicted fish in a specially established "sick tank" (Quarantine). Dropsy can spread from the ill fish, possibly causing stress among the other fish in the tank community. This extra stress may make the others vulnerable to dropsy or other forms of disease.
Treatment may consist of antibiotics targeting the causative agent. They work best in the very early stages of dropsy. A more hands-on approach is to raise the aquarium's temperature a few degrees - slightly higher than usual. Adding Epsom salts (Magnesium sulfate) to the water (at a rate of 20 mg/L) helps to encourage the fish to expel unnecessary damaging fluids.
Siin ka miskit:
