Good food during QT

I've got 2 O Clowns in QT at the moment. I'm feeding pellets that have garlic in them. The larger clown doesn't eat as much as the smaller one. They show no signs of anything at all. They are both very active and come to the glass when I sit down to test the water, feed, and inspect them. IMO, very nice looking clowns that already show some personality.

I was wanting some suggestions on another food to give them as well.

 

Pellets seem ideal while in QT as you can syphon any uneaten portions out.

I use Hikari Marine pellets.
Rod's Foods is my favorite it's frozen and comes in a few different types. A lot of veggies in it as well as meaty sea foods.
Cyclopeez is usually very popular with clowns as well, like candy to them.
