I hate hybrids. Of anything. I know they have their place, but not in my tank.
I don't dislike pacu, I just think that 99.99999% of people who have them shouldn't.
I don't dislike plecos either, but I do dislike the pet store pleco pushers who say everybody NEEDS one. Keeping your nitrates low will do a lot more to get rid of algae and won't take up 12" of tank space.
I hate painted fish of any type, but it's not the fish's fault
i don't car fore armatus, ATF, Dats even though i have a few, p bass, Arapaima gigas,
Lung fish, baramundi. All are cool looking fish. But i have no desire to get any
oh and pirahna.
