Looking for particular fishes

[costacurta]

Hello to all of you,

I leave in Europe (France) and I am looking for some 'hard-to-find'
fishes - for a fresh-water tank. I have tried several websites in France and
Belgium but most do not sell the fishes I want (except poisson-or but they
never have the fishes in stock...).

The fishes I would like to get are the following :
- scatophagus argus
- achirus species (water sole)
- hyp. zebra

I am also interested in coenobita and nerrita.

So my question is : would any of you know a website or a guy who would sell
these fishes ? I believe that in Germany there may be several websites but I
do not know them.

Thanks in advance,

FX
