Catching fish at friends town

[Deligrace]

Hi there,

I need in 6 fish to finish my collection.. (2 regular and 4 deep sea). But those fish are not obtainable in my game atm due to month.. and dont want to tt.
I have a spare ds and game which i dont mind tt. So i can set that game to the right month..

Are there any fish that you cant catch at a friend town? Because im in no luck finding those last ones!
