Just wondering , csn bichirs tolerate salt? I have 3 bichirs in quarantine, but its almost time for them to move into their big tank , currently the big tank has an arowana and i'm currently the tank has 1 tablespoon salt per 10 gallon water, can bichirs take the salt concentration?
the point is why add salt? Both bichirs & Aros are comfortable in a freshwater environment.
The only reason to add salt in a FW tank is to cure ich.
If your fish are healthy, don't add, it could cause salt-resistant ich to develop and killing those are much, much harder.
