Hey Chad,
This is quoted directly from Anthony Calfo's Book of Coral Propagation. Volume one, Version 1.0. Page39.
Quote:
Aquarists who have had experience with plague populations of "aiptasia" (glass anemones) might begin reading this section in shock, horror and disbelief. Nonetheless, Aiptasia anemones are decidedly useful and voracious filter feeders that can be employed in living "scrubbers" to filter particulate and nutrient rich water. They are especially helpful in systems with frequent feedings of prepared or suspended foods. Such systems include, but are not limited to: large fish populations, brine shrimp and rotifer drips, regular feeding of mixed frozen food, and just plain, overfed fish and invertebrate systems. From a commercial point of view, the deliberate culture or containment of the nuissance organisms can serve a greater good in special circumstances such as with coincident Berghia nudibranch breeding programs and fish training for predation on the anemones in other display aquaria can be problematic as they compete for food and space with featured animals and may injure other invertebrates with their stinging tentacles. In a remote downstream vessel, however, they may perform as an efficient, living, mechanical filter.
For Aquarists with plague populations, however, it bears mentioning that Aiptasia indeed are not autotrophic animals and will not grow out of thin air any more than desirable coral species will. Aquarists who have an abundance of Aiptasia anemones in invertebrate displays need to take a closer look at the husbandry technique(s) that allowed the unwanted population to blossom. In most cases, the causative agent was overfeeding or inappropriate feeding techniques (such as frequent passage of thawed packing juice from frozen foodsinto the aquarium... Generally a poor technique when unmonitored). Harnessed, though, glass anemones scrubbing trays or aquaria ate to be used in a grossly similar fashion that algae scrubbing trays are, and for a similar purpose. Raw, nutrient and particle-laden water (ideally from the display overflow on a downstream path for treatment) is fed to an actively cultured colony of Aiptasia. While properly fed and illuminated Aiptasia need little encouragement to propagate, accelerated growth can be achieved by simple laceration of the pedal disc. The proliflc anemones will harvest nutrients quickly and effectively with their numerous grabbing "hands" (the thousands of tentacles in a colony). They are suberb mechanical filters that can be concurrently farmed for food in Berghia nudibranch culture projects.
Some aquarists even use the Aiptasia fields to train certain butterflyfish species to selectively eat glass anemones. The trained fish are then distributed to displays in need of "reef safe" Aiptasia control. The application of deliberately cultured Aiptasia can be multi-faceted and create revenue opportunities for the numerous aquarists desiring to control plgue anemones. And so, love them or hate them, the hungry, fast growing Aiptasia anemones are a boon or plague depending on your perspective and vision. They say thet when life hands you lemons, make lemonade. I don't recommend puree of Aiptasia with sugar over ice, though.

Its not conclusive but its an idea for those wanting to take the plunge.
