Mollies (behavior & salt?)
I just went out and picked up 2 silver mollies and 1 mixed mollie. Now that I brought them home, it occurs to me that they like to be salted.
What kind of impact will salt have on the rest of my tank (planted, assorted tetras [emperors, serpaes, buenoes ares, glowlight], platys, pleco, and frogs).
Conversely, what impact will no salt likely have on the mollies?
Also, are mollies generally aggressive? The 2 silver mollies seem to be territorial and attack each other and any other fish that wander into "their" turf.
