The thing is, Inga, that the water in their habit is indeed "perfect." Don't confuse cloudy (which has no harmful effect on fish) to being stable in parameters. That is what matters. For instance, nitrates at anything much above near-zero can have an impact on many forest fish.
I always acquire wild fish when I can, never tank-raised. They are almost always healthier, more robust, more colourful, and more likely to remain so and even spawn. Provided one can give them the water they need.
Several longtime tank-raised fish are showing signs of malformations and disease due to successive inbreeding, or so many think is the cause.
