Should I combine Omega-3 krill oil capsules and omega-3 fish oil capsules?

So I've been steadily taking 3,000 mg of fish oil capsules each day as part of a diet I'm doing right now. I recently bought Omega-3 krill oils online because I Heard from here they were pretty good, but I was unaware that they were 120 mg each, I got some more fish oil pills but I don't want the krill oils to go to waste, so I'm wondering if maybe I can combine those to get around the 3000 I should take everyday, or is this a bad idea?
