Tetra Krill

[LBDave]

I feed FD krill to my pbass and sometimes my oscars. Silver dollars and Jurupari's also eat it. They love the Tera krill. But none of my fish will eat any other type/ brand of krill. The smell must be involved. After they have spit it out the first time they will not touch again. Days later.
Even my SD's wont eat it. They eat anything!
Has anyone experienced this?
