Most catfish (cories and ottos included) and tetras do not handle salt well. Those are mostly amazonian fish whose environment is acidic with very low amounts of dissolved minerals.

Mollies can go without salt though, especially if you have hard water.

You should find this topic interesting: http/www.fishforums.net/index.php?showto...16&start=16 .

The fish you note as needing salt either need (flounders) or do much better in (mollies) marine salt mix (the stuff for salt water aquariums). Adding this would make the water brackish which would kill fish like otos and tetras.

Just regular 'aquarium salt' is not in any way a substitute, and IMO is completely useless. The topic above explains quite a bit .
