I went there today to pick up a few fish for my backyard pond & found the selection at Big Al's to be quiet varied. The staff was polite and helpful, but I though that Jacob was particularly helpful.
He was very kind and patience when I ask him to avoid putting black fish into my bag, as they would not show up clearly in the water. He also was so polite and offered to carry my bags to the counter for me, and showed me which food to purchase.
Lastly, he was thoughtful enough to give me the tip to not just dump my fish into the pond but to put the bags in the pond first to let the temperatures match and then release them.
Overall wonderful store, wonderful service, just don't wear any fancy shoes as the floor is wet, which, in a fish store, is to be expected.
