Feeding a fishless tank

[cbs49er]

So I lost a couple of fish to disease and now have 2 in quarantine. My DP is 20 gallon with 3 new small zoa frags, 1 stylo, 1 gsp, and 1 blasto. I have 5 blue hermit crabs and might pick up 1 cleaner shrimp tonight. I use a turkey baster to feed the corals once a week but I’m unsure on how much mysis I should drop in there for crabs and to keep it running as normal.

You could just buy some algae wafers. They will sit on the bottom and you casn remove what they dont eat. Or, you can use seaweed and put it on the bottom attached to a clip.
