Λοιπον κυριοι επειδη το ενυδρειο μου εχει γεμισει απο fireworm κανω μια ερευνα για το αν κανουν καλο ή κακο.Εχω βρει μερικες πληροφοριες.
What About What They Eat?
Within the realm of the thousands of bristle worm species, there are certainly varieties that will eat just about everything. Possibly the most impressive are the huge, so-called “bobbit,” worms in the genus Eunice. These awesome animals reportedly can reach about an inch (2.5 cm) in diameter, and be up to 50 feet (15 m) long. They reputedly can launch themselves upwards out of the sand and grab fish up to 4 inches (10 cm) long which they then pull down under the sand to consume. Shades of Dune…

Occasionally, Eunice individuals or some related worms make their way into reef aquaria, probably in live rock, and they may cause problems. However, most bristle worms are not Eunicids! Not only do most worms not cause problems, they are, instead, positively beneficial. The myth that bristle worms are dangerous in reef tanks is a classic case of a little bit of knowledge being a dangerous thing. That kernel of knowledge is a classic. One species of fire worm, Hermodice carunculata, has been known for a long time to eat corals, particularly gorgonians. Unlike most worms, Hermodice is well-protected against predation and is commonly seen crawling around and eating its food. Somewhere in the dim dark pasts of the reef aquarium hobby, some less-than-astute individual made the leap of logic that went something like this: “If Hermodice is a fire worm, and Hermodice eats corals, then all fireworms must eat corals.” Unfortunately, this leap of logic ends with a resounding “splat” as the conclusion collides with reality. Most fireworms don’t eat corals; in fact, it appears that most fire worms, most especially the Eurythoe and Linopherus individuals most commonly found in reef tanks don’t eat anything that is living. These animals are scavengers, and very good ones, at that.

The fire worms most commonly found in reef aquaria are probably the best members of the so-called “clean up crew” that most aquarists can have. They eat excess food, detritus, and the remains of dead or dying individuals. While they will not attack living and healthy animals, they definitely will attack and eat an animal that is damaged and releasing blood or other tissue fluids. Because they are very adept at following scent trails and very active in their search for food, they will often find a dead or dying animal and remove all traces of it in very short order. Their fantastic ability as scavengers is likely the cause of the myth that they eat living prey. Most marine invertebrates will appear to be healthy all the time they are, for example, starving to death. If the animal finally succumbs to malnutrition, the worms will start to clean it up. If an aquarist wanders in and sees this occurring in a tank, they don’t see some diligent janitors. They see their prize specimen being consumed by some “ugly” worms! And, gasp and gadzooks, they think the worms have killed and eaten it! Well, the latter part of that conclusion is true, but the animal that is now food died of something else. As these worms don’t attack and kill animals, neither do their bristles sting corals or sea anemones, and they definitely don’t crawl up into the cavities inside a tridacnid clam, and start eating it. All of these “definite facts” are truly fine examples of aquarium mythology.

What fireworms do do, and do well, is clean up excess uneaten food and remove the recently deceased. Both of these tasks are of vital importance in reef tanks, as even a little time at reef temperatures is sufficient to turn a recently deed animal into a severely fouled aquarium. The beneficial fire worms are just about the most important animals that are available to aquarists for keeping their systems clean and functional. Perhaps, all an aquarist has to do to realize this is to contemplate the amount of “excess food” that it takes to grow a large population of the worms. Then, they can contemplate, what would happen to all that excessive nutrient if the fireworms were absent. In all likelihood, that food would have rotted and gone to foul the aquarium.

The moral of this little tale is that many hard and fast aquarium beliefs are myths. In this case, in particular, many of the “horrible” worms in reef aquaria are not only highly beneficial, but in most cases, absolutely necessary for the systems.
