Ive seen them get in fish at these stores they take no care really in what they are doing their methods are crude at best. So they end up with sick fish right out of the box. then they have these net piles, use the same water container to catch fish etc... they transmit disease all over there store without really giving a hoot.
They also catch fish like crap. For the most part id like to slap the guy up side the head and take the net away from em. Ive seen one or two people that have done a good job at not freaking out the entire tank trying to catch a fish.
when I catch a fish it climbs in the net practically lol! now once they realize after 7 or 8 of them are caught they might not climb in but they still arent hovering at the sides of the tank huffing and puffing looking like rats cornered or something.
It just seems like alot of fish stores have people working for them that know nothing about fish.
