Just spent way to long reading this thread, lol.
I use to live in Adelaide, worked in a aquarium shop there for a year. Never been so broke, had so many fish it was stupid. Have kept almost every native oz fish and love em all. Went through a break up and lost the lot (long story, but was easier to leave with my suitcase)had over 30 tanks including some monster 10x3, 6x2's. I have moved up to Qld now and live on the hill over looking Somerset dam. Am in the process of starting again. only on my 4th tank but the bug has bit and im sure it wont take too long to get back to my fishy heven.
