Help selecting a hungry fish

[Caleb1266]

I need a fish that likes to clean up the scraps. I would just like to reduce the food waste and leftover food hitting the sand or filtration. Doesn’t need to be big just an active fish with a high metabolism. I am thinking a wrasse or something like that. Let me know what hungry fish you have and post a pic. Will be going in an 8’ tank so it will have room to swim. Thanks

I'd look at some of the sand sifter gobies

In my limited experience, I can say that my sergeant major eats a lot and often. He’s 4” long and cleans up food that falls to the bottom as well as food floating on the surface.
