Maidenhead Aquatics are across the South of England usually based with Wyevale garden centres. This one is a large shop with lots of tanks for all ages and beginners and experts alike. Everything you could need to get started, modify or kit a tank for cold, tropical, or marine fish. As well as a huge selection of fish, mostly tropical, but marine and coldwater a plenty. Many species I’d never seen before so rather exciting options for my tank. Prices cheaper than most the local fish shops I’ve seen, and the fish look happy and healthy. The staff are friendly, sometimes lacking in number, but they know what they’re talking about when you ask questions! Always go here first for when I’m looking for aquatics supplies and fish.
