And most employees at petsmart don't have a clue. The last time I bought fish from them was a few years ago. I was stocking my 125 (it was heavily planted at the time) and it was during the $1 cardinal tetra sale should have seen the girl's face when I told her I wanted all of them lol it ended up being 75 or so. Told the girl they were going in a 55 but I had a huge filter hooked up to handle the bio load, she said "oh, they should be fine then" dummy!! Lol
