That depends. In the Sinnoh Pokedex, #80 is Barboach. In the National Pokedex, #80 is Slowbro.
level your Pokemon up to 80
it's barboach. You can get it by battling or fishing it with a super rod.

Barboach and it's in mt.coronet
Well unfortunately you can not catch it in diamond. The Pokemon is slowbro if you did not know and if you really want one you can trade it over from a leaf green or fire red.
In Pokemon Diamond, if you have the sinnoh pokedex(that means you have not found all the Pokemon in the sinnoh region)number 80 is barboach. If you have the national pokedex, number 80 is slowbro. I hope that helps.
