I just use the amount of salt listed on the box of aquarium salt for tropical fish and I have had DAF for 2 months w/ salt in the tanks. I have had to used malichite green for
ICH once they survived through that, and they do fine with stress zyme, stress coat also. However I have no snails.
I also have 2 frogs I just think that they need company.... I actually got a male and female by luck. and they have been breeding..
I completly love them! they are an awesome addition to a community tank...
beware though any fish w/ larger fins they can tear their fins w/ their claws.
