I don't think this one has been mentioned yet, but for some reason I can't stand getting the Zebra Turkeyfish .-. just let me farm Barred Knifejaw's in peace!!!
the sea bass and black bass. sometimes I'll get so angry that I'll release the black bass in the ocean and the sea bass in the river so they die. kind of morbid now that I type it out lmao
The sea bass, black bass and horse mackerel have been my mortal enemies since wild world, but at least they look better in NH I used to hate the octopus, but now I kinda miss it
OMG you named my top 3 hated fish lol. Also getting pretty annoyed with catching squid. Oh! And the stupid suckerfish. Every time I come across a fish with a fin, I start singing "Maybe shark, Doo Doo Doo Doo!" and my oldest child comes running. When it turns out to be that stupid suckerfish, my kid gets more disappointed than me lol. So yeah, maybe it's the worst lol.
