I started reading cover to cover, and wasn't overly impressed. I got to the fresh water Q+A section. The second question answered by their "expert" was about balasharks, someone was asking how many could fit in a 55 gallon. I thought, oh great, he's going to respond that these fish get quite large, and no more than 2, possibly 3, should be kept in that size tank. He started out fine, get quite large, etc etc; but then said that more important is that it would look really cool to see a dozen or so swimming around in your tank, and as they grow, you can just weed them out! I was floored. That doesn't sound like a hobbyist to me, not one I'd like to meet anyway.
There were a couple other opinions in there I wasn't too keen on either. Some comment about staying away from forums because of people that think they're experts (like they have any room to talk...) Wonderful pictures and species bios though, but that thing about the balas just turned me off completely.
Thanks for listening
