+1. It's the most common use for the word in fish keeping.
Here's a quick definition: In biology, detritus (pronounced dee-try-tus) is dead particulate organic material (as opposed to dissolved organic material). It typically includes the bodies or fragments of dead organisms as well as fecal material. Detritus is typically colonized by communities of microorganisms which act to decompose (or remineralize) the material.
