you can’t deny this specimen in particular is exceptionally well cared for, the water is clean and u have to give the keeper credit/respect for that.
Not knowing the NO3 reading I can't know how clean the water is so I didn't comment on that. I would consider it clean if the NO3 was 5 ppm or less, taking duanes' advice on exactly what constitutes clean water.
Thats all that matters
Only clean water? So whether or not the fish can also reach full speed/have enough swimming space to exercise, turn around as it would in the wild without having to bend, and have enough tank space for some stimulating decor doesn't matter?
PS: I have seen giant gourami at the zoo before, in a much larger tank than a 568 liter (probably about 7-9 meters). They were swimming at a reasonable pace and quite energetically, which is a very strong indicator to me that Charlie would benefit exercise-wise with some more space.
U can have a large tank that meets fictional requirements and keep chit water. It goes both ways.
Not entirely sure what you mean here?
Things like autodrip systems are far more beneficial to fish husbandry than space.
I cannot agree with you here. Lack of space makes for lack of exercise and lack of stimulation, both of which lead to a very dull existence for a fish.
It's common sense that exercising space is beneficial, and there are studies proving stimulation is also important for fish:
Enriched environment in aquaculture enhances the survival of fish from bacterial disease
A new study has revealed that enriched rearing of juvenile fish significantly enhances the survival of fish from bacterial infection commonly seen in rearing conditions. That may also improve the post release survival of the fish after stocking into the wild.

Therefore, to reduce stress and prevent a dull existence, I would rank space right up there with autodrip and similar.
Space does not make you a better fish keeper/care provider.
It does, for the reasons above.
Spend some time learning how to keep the space u have better rather than thinking a bigger tank is always the answer.
It is far better for the fish to choose fish that can fit in the space you have. That is what I am doing - so the answer for me is to choose fish suitable for the space I have, as stated.
It will make u a better care provider/keeper.
So what you are saying is, disregarding space in favor of only water quality (which leads to a dull existence for fish) will make me a better keeper? Sorry but I really can't get on board with that.
If u want to be the “loach king”… start reading about auto drip systems
I actually read Loaches Online, where consideration for the welfare of loaches and suchlike is given a lot of thought beyond water quality, extending to psychological and physiological requirements.
