In NZ it’s only goldfish, we aren’t allowed the others.

@Omero Combi oh thank you. I did a lot of searching and didn’t find this info, so well done. There are a few potential options there so I will continue researching those. Thank you.

Kia ora Omero, and thanks for the warm welcome. Yes, we are very blessed to live where we do, it's been/still is, a lot of work to get here but so worth it! That's awesome that you have got to spend time over in NZ. I have joined this group to help my homeschooled 10 year old with his new project. We were talking about food security and diversification of food supplies (and income stream) and building an aquaponics system is what he came up with. We will only be looking at a small scale system but I think it will be a really good challenge and learning opportunity for him (and me).

@Ruggero Conti Thank you.
