As far as I know, only brackish water fish will require salts.blue_gourami45 said:Apparently some of the fish require it (so the labels say).
They are probably using it for emergencies. I wouldn't use the salt until necessary. We don't want our FW tanks to turn into marine, do we?fishyfan said:Hmm the place where I got all my fish said they put salt in all their tanks as well...so I certainly didn't want to take them from salty water to water with no salt. Now I'm a bit confused...They're all doing really well though, active and happy!
