best setup for catfishing in fishing planet

Use the Rod Holder with the highest capacity, preferably one with it's own Bite Alarms, if you can get it (not needed, but nice to have, anyway). If you are fishing in the hotspot right off the Floating Dock in Michigan, then use a Floro Leader, because nothing that can cut your line bites there and this will allow you to catch more fish, including Sturgeon (witch are even bigger, badder, and more valuable than the Blues). This is a place you will almost HAVE to spend Baitcoins, as heavier Leaders are level locked. If you are fishing someplace like Louisiana where Gar frequent the same waters as the Blue Cats, then you will need a Titanium Leader. However, these are big, heavy fish, and you might have to use Braided until you go up a couple of levels and can get Floro that it heavy duty enough. 6/0-10/0 hooks, Barbless if you have the Baitcoins (this gives you bonus Exp.) with Duck Muscle Meat (it's cheap, effective, and can catch things like Sturgeon as well). Heaviest bottom rod you can get at your level.
