Newfishgirl March 30, 2016 Share March 30, 2016 I have been finding tiny white nudibranchs in my tank and I am not sure if these are bad or good? It's not a lot, but maybe 3-4 in a 4 month time period. I did all my frags when I get them in RPS out. I did add some berghia nudibranchs years ago but thought they had all died. Could these little guys be off spring? How do I tell the good ones from the bad? Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Squishie89 March 30, 2016 Share March 30, 2016 Are you sure they are nudis and not flatworms? Link to comment Share on other sites More sharing options...
Newfishgirl March 30, 2016 Author Share March 30, 2016 Yes. It had antenna and feather like body like my berghia Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
AlanM March 30, 2016 Share March 30, 2016 Look for damage in your montipora corals. You may find more nudis on and under them. If so, they are montipora eating nudibranchs, not berghia. Link to comment Share on other sites More sharing options...
Origami March 30, 2016 Share March 30, 2016 Do you have any montipora in your tank? Could they be montipora-eating nudibranchs? Link to comment Share on other sites More sharing options...
Jon Lazar March 30, 2016 Share March 30, 2016 Another vote for montipora eating nudibranchs. Dips tend to kill the live nudis, but not the eggs. Then the eggs hatch and you start seeing nudis again. Link to comment Share on other sites More sharing options...

Newfishgirl March 30, 2016 Author Share March 30, 2016 I think they are the monti eating nudibranch. I've noticed small patches of STN on my montis and now I know why. The only way I think I could have gotten them is a huge chalice coral I purchased. I dipped it for 20 min but it had lots of crevices and perhaps the dip didn't get all the way in. Either way I've caught it fast enough and I'll be looking for a possum or pink streaked wrasse to take care of them Sent from my iPhone using Tapatalk Link to comment Share on other sites More sharing options...
Jon Lazar April 2, 2016 Share April 2, 2016 What did you use to dip the coral? Dips like Revive won't usually kill the eggs of pests, IME. So if there are eggs present on the corals when you dip it, you'll still have pests in a couple of weeks. Link to comment Share on other sites More sharing options...
