I don't think anyone's hating the guy. (at least, I'm not sure about Biff! LOL) I think people just hate what he's doing. We try our best to keep people educated, but it gets blown to bits when people like that guy post a video of his "cool looking 5 gal tank that's been up for a cool month!". People who don't want to do the research will say "Well, this guy did it!" Ignorance feeds ignorance.
I pretty much just said "Poor fish! A one month old tank is not an awesome feat, and neither is your 5 gallon setup" or something like that. Biff left a long "Bifferism" that wasn't as biting as she normally goes, but it was still to the point.
Others commented similar rants -- that this is not a proper setup, too many fish, they will die, etc. Not one person left a positive comment....unless you count the poster himself, who justified the first negative comment by saying "This is a one month old tank!"
