On the upcoming season of "Shark Tank," which premiers Sunday night on Disney's (DIS) ABC, Robert Herjavec said he and his fellow sharks were arguing with reality TV start Bethenny Frankel.

Frankel, and other notable figures such as billionaire Richard Branson and Alex Rodriguez, served as guest sharks on this season.

"Having Bethenny Frankel on there really brought it down to a "Real Housewives" kind of show - we were arguing and bickering just like on her show," Herjavec said in an interview with TheStreet.

Herjavec was impressed with the guest sharks' ability to spot holes in people's businesses.

"Bethenny and I were bidding on this big business at the end - we saw the same business - we all saw the same problems - but we saw different opportunities," he said. 

Here's what Herjavec said about the massive Equifax (EFX) hack:
