As they haven't been listed yet, and it's the only store in my area I can reach (public transport, on foot or by taxi):-
Hollybush Garden Centre and Aquatics
500 yards from J11 of the M6, on the A462.
Plants: frankly they are rubbish for plants, mainly as the tanks they keep them in are poorly lit so the plants all look half dead, they also sell a lot of plants that aren't true aquatics, like dracena. Annoying really as the same plants are in pots in their house plant section.
Equipment: A good selection, including some very nice tanks. Some of their prices seem a little high, but this is compared to internet prices.
FIsh: A good range of livestock, including a coldwater section (including Axlotls), rift lake cichlid section, marine and invertebrate section and of late they have also been stocking quite a few different kinds of freshwater invertebrate, including cherry shrimp, long claw shrimp and bamboo filter shrimp. The livestock I have purchased from here has always been very healthy, and thrived in my aquarium, including my powder blue dwarf gourami. They quarantine all new arrivals in situ.
If you have kids, the miniature train ride is fun, but if you are as big as me (6'5" tall and weigh about 19 stone) it becomes more of a thrill ride as you feel like it's going to tip over at any second.

The staff are the usual mix of people who have never even kept a goldfish, and people who can guess what you are doing just from looking at what you are buying. They tend not to give dodgy advice though, I was present once when they refused to sell angelfish to a lady who was also buying small neon tetras.
In summary: For livestock they are great, for equipment they are ok, for plants you'd do better going elsewhere.
