Hello!
Topic: Dropsy Xenopus frogs.


I'm trying to cope with dropsy for four years.
All my efforts to combat this phenomenon does not bring positive results, but only restraining the rate of development of the disease or phenomenon.

Since I have a subspecies of shportcevoj frogs medium-sized, all five animals live in a 20 liter aquarium for shrimps, pump filter is activated three times a day for 1 hour.
Feeding dry food only moderate Tetra Min XL (summer rarely earthworm).
150pmm water hardness, temperature 23-26 degrees Celsius, rarely is replaced with, normal aquarium smell of, the aquarium grows moderately and only green algae, biological equilibrium is present.
In the water added salt at the rate of a teaspoon (without top) to 10 liters.
At the moment, my frogs has been a slow deterioration of this phenomenon, most symmetrical edema occurs on its hind legs.
These are photos of one individual frogs. Other frogs expressed in varying degrees.
Please provide possible reasons as to avoid this Dropsy of and how to help the frogs. In different forums there is no consensus.
Thanks in advance!
