[coral reefer]

Shrimp are opportunistic omnivores, hence, their ability to forage for food within hard to reach areas areas of your tank such as rockwork and corals that would otherwise be neglected by fish especially.
You would be better off, with the amount of shrimp you plan on maintaining, by offering pellet or even wafer type foods that will sink to the bottom in efforts to allow your benthic feeders, slower feeders and inverts the ability have a better chance of capturing food before the quicker fish species residing in the pelagic region of your tank!
You are correct, that shrimp are awesome and can really add to the diversity, uniqueness and beauty of any reef tank!
Just be careful with the types of coinhabitants you plan on keeping in the same tank as your shrimp and the stability of your water parameters combined with the acclimation and decision on the heathiest species of shrimp will afford you the best chances of success!
Good luck!
