Fish choice for picking at the bottom

[Reefyone]

Hi, I need advice on which fish will do the job of picking pieces of shrimp, fish or other seafood dropping to the tank's bottom during other fish feeding.
This is 1 month old 90 g BB tank, with starboard (kitchen board), live rock, macroalgae, tasseled filefish and valentini puffer, blood shrimp, pincushion urchin and turbo-snail. Or fish- and reef-safe invertebrate(s) for the same function.
I thought about diamond blenny (? big mouthed pale bottom dweller), but it seems they grow big, or mandarin dragonet - there are a lot of cases of keeping them on frozen food, but in bare-bottom tank? I can add content of established 10 gal reef tank into 90g if necessary.
Thanks.

Hello. Welcomr to TRT.

The mandaring is probably not a good choice, most don't eat any other thing but pods.
How about a fast swiming type fish so it can go get the food before it has a chance to settle on the bootom; maybe Antias or a small school of chromis?
I really don't feed my fish so much that it has a chance to settle on the bottom, so I can really think of any other fish.

You could get a serpentine star fish. They usually eat any larger pieces of shrimp or other things off the floor, even if it takes until dark, they'll find it.

This matter must be pretty heavy to make it to your starboard and not get blown around/off it by your current.

Perhaps the settled food should be an indicator that you need more flow directed onto the bottom of the starboard?

Flow is turned off during feeding because this way food settles down in one place - easy to find and remove, not hunt it between/under LR. Fish just don't like some particular pieces and spits them around, next piece of the same food is perfectly OK.
I placed today Maxi-Jet 400 as close to the bottom as possible, directed along long axis of the tank, toward Fluval 404 intake. Tried MJ1200 for this - too strong, fish and invertebrates need place to rest, not constantly fight the current.
Another MJ1200 (in the rear corner) is now directed 45 degrees down toward the tank center, instead of upward as recommended by manufacturer.

Thanks for suggestions, everyone! I'll consider blue-green chromis, just was hoping for one fish to do the work, not several - trying to keep bioload as low as possible. Serpentine star fish was in previous smaller tank - it prefers personal feeding to picking bits and pieces, and it is small.

That's wierd. My fish won't eat if the pumps aren't running. They just look at the food floating around. As soon as the pumps come on and the food gets blown around, bam.

My fish is picking food directly from tweezers, some pieces are spitted off, checked again and some of them eaten. All eat this way - filefish, puffer, clown and cleaner wrasse too (they are in nano-tanks). Wrasse tears food off time from time, check it floating away and picks some pieces.

A Lawnmower or Sailfin Blenny would be good at picking if there is no algae for them to pick at. My yellow watchman goby does a nice job of picking at the bottom. Mandarins have trouble finding food in a tank with no sand.
