This is where we differ with all respect. I've been told by some of the very best in the hobby salt is key, imo. As stressed as GATF can get it seem's to have a calming affect on them. And i don't add pound's of salt. Just a few cup's maybe. He had it in his water from 3''-15''. I've not seen a bigger one in the US?
I have alot of respect for your input. And even more on this type fish (wolf/atf/ect..) Why would you not use salt? Maybe change my mind? Share your knowlage? There's alway's more to learn for sure. And i'd like to know all there is to know about Goliath ATF. So i might keep them Happy for life. Like i hope to do with my 5''er.
