"Silica" just means what the sand is made out of. It is not a size indication. It is, for the most part, the sand that is on a sandy beach. Not fine; not large.
I'm still concerned about the substrate. I see bits that seem too large for the proper sieving for this fish. The substrate is scooped up and 'sieved' for food bits then pass out, through the gill plates. Thus the substrate must be small enough AND consistent in size to accomplish this. These fish do better in substrate of about an average of 1mm or smaller in size, but seem to have problems when the substrate particles contain average sizes in excess of 2.5mm.
Any fish can be quarantined, even if it has special needs. All new acquisitions should be quarantined. Don't give up on that approach. A properly operated quarantine process is less stressful than being put into a display tank with other creatures.
Mysis is not a staple food. Garlic will not help here. This fish needs variety and vitamins along with a fat supplement. You should take some time and read this:

If you don't provide better nutrition and very soon, the fish may not heal as fast as it should, nor will the fish likely live very long on that one food.
