So far I've been to the following aquarium stores:
Menagerie (Parliament/Wellesley) - I've been to the Menagerie recently and picked up some shrimp: Cherries, Red Nose/Rhino (my favourite), Blue, and Bumble Bee. It's the only store that I've been to that had shrimp other than ghost, cherries and amanos. Small selection of plants. They had Hair grass, which I don't often see (perhaps never seen). Aquariums look small and algae filled and they're using those old style corner filters.
Big Als (Steeles/Yonge) - Apparently they have a plant guy there who I haven't met yet. Decent set of plants species that look healthy. The kids who work their don't seem too knowledgeable regarding plants, I have to find this plant guy one day.
Big Als (Mississauga) - lately the plants haven't been looking too good, but they have a good selection of plant species.
Big Als (Oakville) - I've only been there once and they had a good selection of plants that looked healthly. That circular marine tank was a disappointment
I wish it had live coral and such.
SuperPets (Yonge/Lawrence) - Small selection of plants with decent health. Aquariums like very nice and tidy with healthly fish.
PJ Pet Centre (Sherway Gardens) - Nice looking aquariums, clean, healthy. Small selection of plants but generally healthy looking.
PJ Pet Centre (Yorkdale) - Very little plant selection poorly maintained. The absolute worst looking plants I've seen. The prices were priced accordingly, very cheap. But you may be able to revive some plants in your own aquarium under more optimal conditions without spending alot.
It seems the stores with some plant knowledgeable staff have the better quality of plant, both in selections and health.
