Our story
30 years of fishkeeping
A neighbourhood aquatic shop in Eltham, southeast London, where people come back for practical advice and a proper conversation about their tank.
A shop you can walk into
Castle Aquatics has been on Well Hall Road since 1996, which is 30 years of people coming through the door with a question about their tank. It is family-run to this day. The shop sits in a parade behind a blue sign that has been there a long time, and inside there are banks of lit aquariums along the walls with shelves of food, treatments and equipment opposite.
It is the kind of shop where you can stand and watch a tank for ten minutes before deciding anything, and where asking a question does not feel like an imposition. Plenty of our customers started with one small tank and a lot of questions.
We are not trying to be the biggest aquatics retailer in London, or the cheapest. What we can offer is fish you can look at before you buy them, and someone to talk to who keeps fish themselves.
