I thinks it's hard to find somebody with enough knowledge in a store, and most of them would laugh at you if you call them on Sunday night, because your fishes seem to have a problem.
This is all not a problem here. You can discuss, get many opinions, views, and tips, and read honest reviews about where to shop and where not. -Just great!
