Hello Crew,
<Richard>
Five years ago I setup a 215 gallon sps/clam tank. Four years ago when my 55 gallon softie tank sprung a leak I temporarily placed the soft corals, including some discosoma, in the 215. Of course some of the mushrooms came loose and became established in the crevices of the rockwork (Murphy's Law I suppose). Now the mushrooms are completely taking over the tank (even growing directly under 400w halides).
<They can do this...>
I've tried a number of things to control them from manual removal to injecting them with everything from kalk paste to lugol's all to no avail.
They are reproducing faster than I can keep up. Much of my rockwork is part of a dsb retaining wall that I built when I setup the tank so I can't simply remove the rocks that the mushrooms are on. So now I'm faced with either converting the tank to a softie tank or completely tearing it down to remove all of the mushrooms.
<Likely this is the best route...>
A better option for me would be to remove the sps and clams (I have numerous tanks) and then add something that would eat the discosoma. However, I don't know of anything that really eats discosoma. Do you have any suggestions for anything that will definitely eat discosoma?
<Unfortunately, I do not. The few times I've encountered this genus underwater, it has dominated the habitat, with nothing observed that was predating it> Some type of invert, such as a predatory starfish for example, would be ideal since it could easily be moved to one of my fowlr tanks when it has done the job.
Thanks for any suggestions
Richard
