There is no specificrod that you have to use. You can use Old Rod, Good Rod, or Super Rod. I used Old Rod and it worked fine.
the only way to evolve it is to have the feebas at a high BEAUTY status for Pokemon contests. and the best way to do this is to have a feebas with a MODEST nature.
go to mt cornet where the lake part is and use your rods on a specific location yo thib the worlds best Pokemon trainer in the universe.
Modest is really great!
the berry that i use on my feebas was pamtre berry and it turn out well my feebas evolve you can get the pamtre berry on pal park
Diamond is not a Pokemon but i think Arceus is one of the strongest Pokemon ever.
the best Pokemon on diamond would be arceus but you can only get that from action replay, other than that i think the best Pokemon would be giritina..
the best Pokemon for the Pokemon league is definetly latios
Palkia
the best Pokemon in diamond is arceus, but you have to use action replay or wi-fi mystery gift
Feebas can be found in both Pokemon Pearl and Pokemon Diamond by doing the same thing. All you need to do is go to the basement of Mt. Coronet, and fish in the water with either the Good or Super rod. Feebas is found in 4 random tiles which change places daily. The odds of finding Feebas in one of these spots is 80% or so . Try going to the corners of the water. He is usually there.
yes you can but its very rare Four random tiles in the water of the basement in Mt but use your best rod to evolve it get its beauty up the highest by feeding it dry poffins even if it dosent like it
No Arceus is the best Pokemon in Pokémon Diamond.
