I can understand limitations on abilities in the enclosed space of an apartment.
I've considered more or less the keeping of CRS/CBS which seem to be the easiest, or maybe even some cherries.
I've considered the tap water, with distilled water to break down a bit.
or maybe going to an area LFS in between for RO/DI water.
Would love to hear more from people in the area about keeping shrimp.
Each generation imagines itself to be more intelligent than the one that went before it, and wiser than the one that comes after it.
It is not the strongest of the species that survives, nor the most intelligent that survives. It is the one that is the most adaptable to change.
