? on Severums

I bought 2 yellow severums a month or so ago and after doing some
research on them could not find much. "Fish geeks" on line was the only
info I could find on them and even that was little to none. It said
that they get 6in and are ok as a community fish. I have them with
angels, gouramis, kribs, corys, a pleco and a rainbow shark. Does
anyone have any real info about them? Favorite foods? temperament as
they mature? Any info would be great.

Thanks,
Vicki

(wondering if this sweet little yellow fish will turn in to a monster)
