Thanks - I have a 65L tank. I ended up getting a great deal on Trade Me from someone who was leaving the country and needed to offload all his gear, so I have ended up with all kinds of odds and ends: pumps, filters. heaters, test kits, food, fertilizers, a number of smaller tanks etc - so I should be set-up for a while.
My plan is to try a "dirted tank" and with a lot of plants in it. Once established, I'd like to look at maybe adding a small school of Harlequin Rasboras and then something like a Honey Gourami
