Homemade fish food

I recently tried making homemade fish food for my Clownfish.
I used about:
10 whole shrimp
30 small freeze dried krill
1 oz fresh salmon
1 oz frozen whitefish
..25 oz flake food
..25 oz kelp pellets

I blended these into a paste and added gelatin.

It's dark greyish-green color and I'm wondering why the clownfish
won't touch it.
When I put it in the tank they get excited and will "sniff" it but
won't even take a bite. I'm wondering if it's a problem with the
color. I seen them show a preference for pink or yellow in flake
foods.

Or maybe they don't like the texture. It stays mostly solid for about
16 hours in the tank. I've disolved it in warm water and then fed
them the tiny little pieces. They seem ok with that but the pieces
are so small then. It's almost a liquid at that point.

Does anyone have any ideas?
