I just mentioned in another thread that I can't believe there's no natural predator for aefw.
I believe there must be, simply because they would decimate whole reefs if there wasn't a predator.
They seem more common on maricultured pieces. As such if there was no predator there would be serious problems in growing maricultured on the reef.
When the coral comes in they still look good with no obvious signs and they aren't covered in them at all, maybe just a couple come off. This suggests something is keeping them in check before they are removed from the sea.
It would almost be as simple as going to a farm, searching for tell tale bite marks and waiting and watching, possibly difficult if they predate them at night.
Of course if anyone wants to chop in and sponsor me......:celeb3:
Another thing is that they seem to be only on bali pieces, has anyone come across them on oz or fiji stuff?
Could be that whatever eats them doesn't live in lagoons where they grow them but I do believe they do.
I'm fairly sure any acro with a crab in hasn't had them in my tank, it makes sense they would eat them.
For me simply basting works, as long as numbers are small it's ok, the wrasse then devour them. They are only a real problem if nothing is done.
I also don't see the point in dips as it really upsets the acro, basting will remove them, I've heard of people using ro to do this as well which is meant to be even more effective. No dip kills the eggs. I just dip when they go in the tank, but not once they've been in for a while as I find moving them and taking them out causes upset on it's own.
In my tank now I haven't seen eggs for ages but did find a aefw on one piece so there still there. Hopefully I've broken the cycle now but won't hold my breath.
