I like having a variety of dry goods to choose from.
Dead fish aren't the most active fish to watch in my LFS
:/ I like the little labels they have at petsmart. Maybe show the temperment of the fish, how large they get, and what size tank they need.
There's one store by my house that has a really need display tank for plants on sale. They have a strip of masking tape on the front of the tank that says the name of the plant. Then the plants are planted in a row behind the masking tape. This other LFS
just has a bunch of "potted plants" in a tank and you have to guess and see if you got the one you want.
Organization is key!
