I have visited the majority of them in my travel to Houston.

DEFINITELY CITY PETS, they have such a huuge selection and incredible pricing.

Fish Gallery is a really nice, high-end store, cool to go look at but I think their prices are sometimes high.

If you are a SPS fan, then you have to check out the display tank at T&T! They also have a really friendly staff, and some really cool selections, lots of aussie stuff!

Those are the 3 that I stop by everytime I visit the big city!
