Certain fish, like hawkfish for example, are known invertebrate predators. They cruise the aquarium, picking off any unsuspecting shrimp, crabs, or whatever else that catches their attention. Despite their voracious appetite for expensive inverts, predatory fish can’t always eat them all. Larger inverts may be alright in the presence of a small predator, especially those that have small mouths. Having a lot of live rock also helps, as the inverts can hide from and avoid these predators. In the long term though, the fish will get larger and your invert collection will become increasingly at risk. Try feeding your fish regularly to keep their appetite at bay, and perhaps you’ll be able to keep both the predators and your favorite shrimp.
