Fish tank man

Fish Tank Man is a private aquarium operation just outside Barnet in Hertfordshire - the sort of specialist fish keeper's place that's more about serious aquatic enthusiasm than theme park spectacle. You're looking at tropical fish displays, mostly, with the kind of detail and care that appeals to hobbyists rather than casual visitors expecting Nemo in a tank the size of a warehouse.

This isn't a destination you'd drag reluctant kids to for an afternoon. It works best if someone in your group actually knows their cichlids from their tetras, or if you're seriously considering setting up your own tank at home and want to see what's possible. The owner clearly knows their fish, and that passion shows in how the tanks are maintained.

Being based near Barnet, it's within striking distance of several caravan parks - The Mimms is barely a mile and a half away, and Commons Wood is under six miles south - so it could slot into a wider Hertfordshire trip if you're the type who gets excited about specialist collections. Aldenham Country Park is closer still if you want to balance aquatic life with actual outdoor walking.

Before you visit, you'll need to ring ahead or check their current opening hours and any admission charge - this isn't the kind of place with standard tourist facilities. Worth the detour if aquariums genuinely interest you. Not worth planning a trip around otherwise.
