BTW: He's deleted all but one of his videos, presumably because he got called out for his latest video straight up chastising folks for using vernacular / common names when discussing species.
He repeatedly told viewers they "sound stupid" when they do things like call a Plecostomus a "pleco". He wasn't joking either. He sounded genuinely angry.
A user commented that if he was going to be a condescending pedant, he should at least pronounce otocinclus properly. And that he sounds stupid. (He was pronouncing it oto-sink-U-lous.)
12 hours later, and all his vids are gone. Coincidence?
