Can guppys, a alage eater, and a albanio cory tolerate salt in their water?
Some salt is actually beneficial, but don't go dumping in table salt. Goto a pet store and find some aquarium salt. I have some in a small box. It helps reduce stress and promotes heathly gill function. Just don't put too much in, different fish have different tolerances.
Why no NaCl?
Chlorine can be toxic to fish.
salt tolerance: there is a range of tolerable salt concentrations for those species (you'll have to do the research...or some other helpful member )
no NaCl: true saltwater is more than just H2O + NaCl...you wouldn't be simulating the proper natural conditions with just table salt
