HELP PLEASE! Nudibranchs

[mario420]

I found the spiral eggs growing on my African blue hornets. I took out all zoas and immediately dipped them in Coral RX pro. I scene many large nudi's fall off and die shortly later during dip.

My main questions is how often do I need to dip these to stop spreading. I pulled off the visible eggs. I am sure there are some left. Does anybody know the life cycle of the nudibranch i.e hatching to full adult to lay eggs. Also how long before the eggs will hatch?

Thank you all for help

Not sure but a yellow coris wrasse would destroy any nudi

Flat worm exit is actually one of the best ways to knock out nudis. They recommend dosing it, waiting a week and then dosing it again as it does not kill the eggs.

The dip was a great first step

Scraping the eggs was the best second step

Repeating those 2 steps in a week and every week until you don't find any nudi's or egg sacks is your safest bet.

My favorite fish for a zoa tank is a yellow coris wrasse as stated above. I always have one. They are so acrobatic as they hunt. (say goodbye to pods)

IMO using flatworm exit will kill adult nudi's,
however it will also do a number on your biological habitat in your tank.
That is the health of your tank and you take the chance of a mini cycle starting.

Hope you have great luck and keep us posted.

I know this is really old but by adding the yellow coris it cured my problems.
