    Hi Guys

    I bought some frags and corals this weekend and did the normal Medicoral dip for pests. On further inspection of the open brain/donut, I noticed these flat slimy brown creatures - about 6 on this specimen.

    I managed with a bit of difficulty to remove two with my finger, so any ideas will be welcome. I decided not to remove the others incase any fragments start spreading further. The coral is in a holding tank for now. What is it and how best to get rid of it. As a matter of interest, will a RO dip be safe for this coral

    Thx

    looks like flat worms. Get yourself a bottle of Coral RX and use that. Good thinking with putting the corals in a holding tank

    Hey Tremayn, I was also thinking its flat worm, but arent flat worms much smaller at around 5mm, these guys range from 1.5 to 2cm round.

    Does Coral RX kill flatworms ??

    Here is a link on flatworms with pics and this pest is nothing like it - maybe a variant of some sorts http://www.wetwebmedia.com/flatworms.htm

    Those look like flatworms. There are lots of different species and some actually get rather large.
    If you cant get hold of Coral Rx, an iodine dip should also kill them.

    From what I know, coral rx works the best. Give that a try. The people who used it said you just see things running out of the rocks and corals and dropping dead :)

    Now what would a person do if it's actually on you'r Coral in you'r Tank..? The same...take out..dip..rinse..put back..? Do they latch onto the Coral and stay there or do they circulate in a persons Tank...?

    I am still not convinced that these flatworms are bad for coral, but personally would never take a chance, agree with [MENTION]@459b[/MENTION], Coral RX dip. If it is flatworm, it will pop off.

    You may want to run an experiment for us to learn more about them and leave it to see if it spreads ;)

    Looks like snail/clam/invert eating Polyclad flatworm. Imo, it's probably not eating your coral. I think it's more likely hunting for other inverts that might be on and around the coral.

    Yeah, they get a bad rap, but must of them are harmless. The only really bad ones I can think of are the acropora and montipora eating flatworms. They're no fun.
