So I decided to spend quite a bit of time chain fishing cos shinies, and I've found it's the most effective method.
I may have ended up with 3 spare shiny poliwhirl.
I'm looking for a shiny for shiny trade-I should point out that all 3 have terrible IVs.
I'd particularly like a shiny staryu if anyone with X happens to have picked one up, but I'm open to offers.
