When I had my first stint in the hobby years ago I was only young and it never once registered in my mind that where I was living at the time, and the partner I had, may very well change, and not just once or twice either, lol.
If I remember rightly I had piranhas at the time and life dealt me one of those bum deals. I had to shift my tank and fish about, and as you very well know it is no fun whatsoever. In fact I took such a dislike to it I decided to come out of the hobby until I was more settled and the risk of moving again was practically zero. That was in the early 2000's.
I married in 2014 and then we moved into our final house in 2015, with no plans to move in the future. I felt extremely settled and so decided to give the hobby another go. Six years later and I'm up to my neck in it again, and loving it.
That moving thread of yours and all the hassle and bad luck you had is the most traumatic thread I've ever read on here, lol.
