Poliwag is not catchable in Ruby, Saphire or Emerald.
You can catch feebas with any type of rod in Pokemon sapphire,ruby and emerald but a super rod is the best-good rods and old rods work to but they r harder to catch feebas with :^] I tried that but i just got a whole bunch of carvanas. Its probaly the same catch rate with all the rods. With an old rod, basically every second catch on a Feebas tile will be a Feebas. Also, with the old rod, you usually just have to press once to pull up the catch. With a super rod every catch on a Feebas tile will be a Feebas, but you will often have to press 5-6 times to pull up the catch. if you use a old rod it only catches magicarps,a good rod will only catch medeaim lvl Pokemon and a super rod will catch every Pokemon.its better to use a super rod
Route 128 or Evergrande City (Super Rod)
on rount 119 note use super rod
you use the good rod in a river or somewhere :/
You need to have Good Rod to catch Staryu. Fish with the Good Rod in Olevine City (Johto) and you'll catch Staryu sooner or later ;)

You can find them if you fish in routes 102, 117 or in the water at Petalburg city with a good rod.

You can't catch a feebas in the Hoenn region. In the Sinnoh region you could catch it with any rod. It doesn't matter. :0)
Use the Super Rod in Lilycove City.
