If you dont have any natural predators in your tank the population of
those mutant starfish will keep growing. I had some in my 92 and at one point I was picking out 60-70 (my daughter enjoyed keeping count) of them at least once a week. They killed a beautifully colored pipe organ colony I had so they do harm to corals. I couldnt keep up with them so I finally got a harlequen (sp) shrimp that cleaned them out.

awww, here we go, another pest i am embracing... geese, does it even end. I
guess when your a natural breeder like me, then any life in the tank that shows up is wonderful and grand.. they were apparent hitchikers from lfs on a rock i had suspected, and there is total about 20-30 of them. never had an explosion problem. one thing you guys are missing, is when you pull these species out, you are upsetting a balance that you yourself correct later by selected algae removals or something. But what i am apaprently doing is letting the tank dictate what kind of explosion it needs, this has been going on for years. about 5 years ago it had a small(about 1/16th inch) snail explosion(thousands), and when they did their job after about a year or two, they started dying off naturally, and now theres only a hundred or so left, which means i can barely ever find ONE if i look hard enough. then one time i had a GHA explosion, and after battling with it for months, i gave up, and had faith that the tank was in a good enough state to combat it, because of all the hard work of nurturing these biological successive explosions, all of which was building a biological ecosystem. so, when i let the GHA get outta control, it took over the whole tank, like the snails at one time, and then it started to get these gel webs forming around them, and worms started breeding by teh thousands in various area, and from teh inside out, from teh roots up, the worms ate away the gha all up and the tank was then endowed with a gha killer program, along with its snail killer system, its cyano killer system, and then the worms churned up the substrate liko no other and created the ultimate anerobic system, so then i had a tank from top to bottom that had superb substrate, all the way to thousands of algae killers ready to spawn at a moments notice, etc... it was a beautiful story, that took years to unfold. Natural Biological Control. So, these Asternias are a part of the tank history, they are staying thats for sure!!! hehe. ok, if they get out of hand, ibviously the next step for me would be to introduce a predator, because these reactions are growing bigger than an aquarium can handle without the proper predators introduced. my point being is we cant exactly expect an emerald crab to spawn from fish juice. my tank has hit its limit on the big scale, its up to me to place the proper predators in the tank. The small scale ractions however, my tank has an uncanny ability to respond in different ways to many problems. i even had a killer algae(caulerpa, taxifolia?) problem, and the system combatted that too. right now theres only about 33% coralline coverage, some rocks completely covered thick in purple, most others in hto pinkish, some new thin light pink. Anyway, the primary difference between the way i do ti above, and most people do it is this. most people buy expensive pieces, so they need to hack off all other dangerous life in their tank, i could never do that. instead, i let that other life, that others call dangerous, or weeds, or pests, and i use them as they were intended, etc..... Its kind of a fun approach to reefing, and definetely is the easiest poor mans way to reef. :-) "wxtbs" wrote in message oups.com...

We must be talking about two different starfish, because if their growth in population is so fast and their diet consist of corals, you would see them feeding on live corals all the time... Do you ? I know they reproduce in large numbers in tanks which have NO corals! At least no corals that have been eaten by them... I have them in large numbers in my refugium, where there is NO corals at all. How would they survive on non-coral diet ? Starfish often eat bacteria growth, so if your coral died, and was consumed by bacteria, these were feeding grounds for stars. Do you see these stars on any other live corals in your tank ? |
