Well, I got my Feebas in about 2 hours because you never know which tiles the Feebas usually hang out on (they changes everyday). I searched in the lake closest to the long grass. I CHECKED THE WHOLE DANG LAKE AND ONLY FOUND 1 FEEBAS! To catch Feebas you have to be a patient person because it takes a REALLY LONG TIME TO FIND. I ended up catching a Lv. 27 female Feebas. I fished with a GOOD ROD! In case you don't have one you get the good rod by Mauville city. Once you get surf you can cross the lake and talk to the fisherman on the other side. Back to the 'Feebas catching'. I fish with a super rod on almost half the lake and then I tried the good rod. I hope you get as lucky as I did and catch a really strong Feebas! P.S. To evolve Feebas just raise it's Beauty as much as you can! Good Luck! if you just want to see a feebas when you battle the eighth gym leader cross the first bit of ice the walk on a square block of ice twice on the second bit and there will be two trainers the one on the right has two feebas's.
U can find feebas in Route 119.
The Super Rod is the only Rod that you can use to encounter Feebas in Emerald.

You can find Feebas along route 119 in Pokemon Emerald. Feebas is often over looked similar to Magikarp due to its dull wit and unattractive appearance.
