Another ID thread. Am I in trouble???

Sigh. Thanks for the reply.

You will probably need to be more aggressive than muck has suggested to be rid of these pests. They will sit on corals and block the light so the corals starve to death. If you work on lowering nutrients you will often lower the numbers of flatworms. Siphoning at least weekly...you could try one of those gravel vacuums that has a pump and a bag to catch detritus (in this case flatworms) without removing water. Works like a charm. Once you have the population lowered (you have LOTS), then a product called Flat Worm Exit works very well to be rid of the last remaining of the pests. Some Wrasses may eat flatworms (it is individual), and make good prophylactics, but are not usually capable of depleting a population like yours.

Do some Googling...lots of info.

Grrr thanks for the reply. Will have to do the usual google help type stuff. At the level these things are at im sure to find atleast a couple of others who have suffered this one.

While it will not relieve your problem completely, as Mykas instructions will certainly put you on track to do, bumpin up your flow will reduce thier numbers significantly.


I used to have them as bad as you judging by your pics but when I added another 80% of flow in my tank they became barely noticeable and only visible in cracks and pockets where the water movement is minimal.


I have read of people bumping up flow and then adding a biological solution (like a wrasse) until they are all gone to the eye and then putting flow back to normal with good results.

I have also found that Blue Velvet Headshields can really do a number on these things and since this particular flatworm isn't detrimental unless concentrated in large numbers you wind up with a sustainable diet for a pretty cool reef inhabitant who needs these flatworms as a specialized diet.

Please keep in mind that as these little guys die, they give off a poison that is no good for your tank.

If you choose to get rid of them via a chemical means, like flatworm exit for example, siphon as many out as you can then be ready to siphon them as they die.

If you could find a blue velvet, that would be the best option but I rarely see them in stores so best of luck.

If you want to go the Blue Velvet route... give Ken a call at BlueWorld. Im sure he will bring one in for you.

Blue Velvet Nudibranchs are sensitive, and don't acclimate very well, so don't be surprised if it dies before it eats any. the advice to up the flow is great advice, I forgot to mention it.
