Last month I got a 54L tank (gift from my gf) and it's a pleasure to be back again to this hobby!
I had a 35L aquarium when I was 13 yrs old, and kept it for 4 years.
At that time - 10 yrs ago - I didn't have internet access, my source of information was very very limited. Stores in my hometown had a quiet nice variety of cheap fishes for the time (well, most of your fishes probably come from my country
), but a very poor knowledge about fish keeping...
I remember that the pH test was the only test available, and everything happened around this. I was always thriving to keep it around 7, while kH
and gH "didn't even exist"
Not sure if this hobby improved that much along 10 years, or if things have been always like this in the old continent.
