Forgot to answer question. They are much better at sticking to actual aquatic plants and emergent plants. At least at my local one that is. They are also very helpful at petland when they're not selling dogs that is. They will happily explain fish and plants and not just sell you things just for their benifit.
Petco however, horrible, last time I went in they had all kinds of plants in the water that werent aquatic.
