Part of owning an aquarium means coming across a dead or dying fish from time to time. It is an unavoidable aspect that totally sucks, but just because a fish dies doesn’t mean you have to condemn its soul to an eternity on the porcelain express. If you have a predator tank or any sort of meat eating cleaners in your normal cleanup crew, then don’t waste a good opportunity to feed them a natural food item every once in a while. By this we mean take advantage of the fish’s death by letting a more natural processes take over. Of course, you want to avoid feeding really sick fish to a healthy predator, as the ailment could be transmitted to the healthy fish. In this case, it’s best to let a large starfish or other invertebrate to take care of the problem. For obvious reasons, it is best to use a freshly dead fish, as opposed to one that has decayed, even if just a little.
