Hiya,
Can give you some names that will show up on google
I use certain ones for certain things
The Hollybush (just outside cannock) some know quite a bit then again lots there don't lol, large selection for sure, hit n miss for hard to get stock though
Grassmere (approx 1mile from muckley corner island heading towards cannock way off the A5) must add they aint very large for fish but boy i got some beautiful barbs/loaches from there and they did have a great variety of tetra's (think we've bought them all now lmao)
Stafford, (right inside the back of the old Reynolds Bar) can't rem name offhand but you can google stafford petshops etc, decent and was having all led lighting installed last time i went !! decent broad selection of fish
Stafford again, Pets @ Home of all places, found the fish there to be excellent but obviously just basic species (cannock i avoid plague, ignorant/lame/idiotic staff)
CD Aquatics, can never rem the place name but it's litterally just outside cannock, small selection but sometimes some nice hard to get stock
If you want a decent run out, i'd recommend A5 Aquatics, head towards nuneaton down the A5 it's just passed MIRA (either shower manufacturers or a car test place ? ) great for actually having items on racks not hidden without prices and behind serving counters
Did goto a shop by asda in walsall, bought some algae wafers and walked away, though it was geared towards marine not tropical so wasn't much use to me just having mollies etc in stock
Not been yet, keep on thinking of going though, Shirley Aquatics
Food for thought for ya
Tony
