As for the question, and as an afterthought to my own setting up in the hobby, I think it's always best to go with whatever fish you like in the size and other attributes, that suit your local water supply.
The amount of faffing about trying to get water to suit the fish is akin to the 1st steps to insanity.
Ide agree with you but I don’t have a hobby, I don’t work because I care for my sick wife , so I don’t have really anything to do for a lot of the day. Faffing around with fish tank water is actually what keeps me sane
