Tip of the Day – 2/11/10


Iodine dips don’t always get every parasite. This especially holds true for eggs. For example, Acorpora Eating Flatworms (AEFW) lay eggs on the branches of Acro corals. These eggs are not fazed by any sort of dipping method. The only way to remove them is through close inspection and manual removal, followed by quarantining the coral.

  • Hi,
    I don't know much about using Iodine. Could we simply make a few treatment in the same week to eventually get them all before they can lay eggs?


    • well, the eggs are usually already on the coral, as are the flatworms and other parasites. the iodine might kill or at least knock off the parasites, but the eggs will remain. if you put the coral into the tank, the eggs will hatch. if you put the coral into a quarantine tank for a short time and dip it in a water/iodine solution every day, then you will more than likely get all of the hatched parasites. the life cycle for aefw's is short. so they will hatch in no time. just keep an eye out as they blend in very well.

  • Thanks! I have some iodine here but never tried it. I'll give it a try next time I quarantine corals.
