why no war?

Maybe is a silly question but why in the ancient sources is no
mention about wars between goths and getae?
There are mentioned wars between gepidae and goths ( even if
almost same folks , or folks of the same stock) but nothing
about goths versus getae. That remember me about one topic
here on cybalist ( I guess is more as one year ), where , if
I am not wrong, George Kynsch tried to see if there is
something more between getae and goths and where first the
confusion first should have been ( Orosius , Iordanes and so
on)
