Help for Beginners

Here at Marine Fish World we’re super-enthusiastic about the joys and benefits of keeping a marine aquarium, and so we’re eager to share our knowledge and inspire others to become ardent aquarists.

If you’ve ever sat and contemplated an aquarium you’ll understand how calming it is to lose yourself in that peaceful subaquatic environment. There’s no doubt that having a fish tank at home or in the workplace enhances your physical and mental well-being.

At our Milton Keynes store we have regular visits from children with varying types of autism, whose parents bring them to watch the fish as a form of therapy – and they all enjoy being absorbed by the tranquil and serene undersea environment.

If you’d like help with setting up your own customised aquarium, or if you’re an experienced fish fancier with some questions, just get in touch, and we’ll be delighted to help.

Great little shop. Owner is very knowledgeable and very keen to help. I've just moved to the area and was offered a lot of help in resetting my tank. Some other locals in the shop patiently waited for us to be served and were on first name terms, a very good sign of great service. Can't wait to go back to restock my tank.

Fab shop, full of advice (well needed in my case) and will sell you what you need, not the most expensive thing. I’m planning a size upgrade to my tropical setup soon and will definitely be coming back here to make sure I get the right accessories.

Visited shop for first time recently with my 13 yr old son who is a keen marine keeper. Purchased a new tank and the advice was absolutely perfect. We were not rushed at all. My son can’t wait too return 🙂 thank you
