just found zoanthid eating nudibranch, are there more?

[sabazerehi]

i just found a zoanthid eating nudibranch on the glass of my tank this morning which i hope will explain why my zoas haven't been opening for the past few weeks. however, it is extremely small and i have several zoa colonies that are seperated from each other and they're all not opening. does that mean more nudibranches? and if so what should i do to get rid of them? the one i found looks just like the one in this link: http://melevsreef.com/id/dc_nudibranch.html
and it's only like 2mm long.

they are like cockroaches-if you see 1 you might have 1000. good luck with the dip!

watch your tank at night have a turkey blaster in hand and sux them up. dip what you can and look for eggs you can scrape off.

also like to say not all nudi's are zoa eating. picture might be helpful. there are some that just eat algea. if you have zoa's more then likely they are the zoa eating kind.

the link above shows a pic of what i have, but mine is way too small to get a good picture of. so what kind of dip should i be doing if i should even do one at all? i'll keep a look out for them at night as well

iodine

There was just a study published in Reef Hobbyist Magazine that talks all about this issue. You might want to stop into your local fish store and pick one up. It suggests using Salifert's Flatworm Exit as a dip for nudibranch. The study showed the same death of nudibranch as with iodine but with less side effects to the zoos. Just a thought.

i will definitely check that out and ask about it. thanks

If this is true then zoa eating nudibranch are not to be feared any more than red bugs. I wasnt aware of any in safe in-tank treatments to erradicate them.

anybody have a link to this??
