Contacts in the UK?

[Hari]

Hi all,

I`m Ben and I would like to keep some Ranitomeya at some point.
But since I pretty much need everything, beginning with a 50x50x80 cm tank, I would like to ask this community for some links/contacts in the UK for frogs as well as retailers for plants, lights, etc.
Preferrably in the North West but all UK contacts are appreciated.

Many many thanks in advance!

Ben
