Hi Sam
It is a good parent/child hobby to get into as the whole family can get involved. It is also a good hobby to help with science projects for the school Science Fairs
It has been there a few years now. Very small but excellent quality fish and more than the usual species often on offer. They also have a good range of carnivorous plants.
Welcome. Redwoods is fine but my favourite is Organism, corner Ilam & Clyde Rds.
Check out Critter Kingdom (stanmore Rd & Blenheim Rd) and Pet World 475 Ferry Rd. No harm in looking 8)
