White Nudi on SPS

[Zac]

Recently found about 5-6 white nudis on my sps .. Any idea what are those ? Need to remove ?

most possibly found on your monti cap. Get yellow wrasses to consume them

Likely the montipora eating nudi. It target all kinds of monti including digitata as digi is part of montipora family.

The difficult part of wiping them out is they are generally active during night time after all lights are out.

The best way to eliminate them is to take out the affected monti. Fresh water dip is the most effective but it will likely kill the monti too.

I have not tried other medication like coral RX before. it may be worth a try.

Be mentally prepared to lost your colony or colonies as this nudi had devastating effect. Depending on how much nudi had infested the tank.

I used to have a huge colony of plating monti more than 8" across. The nudi basically "finished" it within 1 week+.

Maybe other expert here can give you more advise.

Good luck.

Thanks all for the advice..

Get wrasse. My six line did the job pretty well.

Best way to counter encounter nudi:

Dip ur infected coral into Coral RX!

2nd: Get a Six line wrasse!!

Your tank will be free of nudi ~~

Ya. try google for Montipora eating nudi.

You probably find a tons of info shared on the site.

Do keep in mind once the nudi is in your main tank.

The best method is still to remove the colony as wrasse will help to a certain degree as this kind of nudi is generally active only in the night when the wrasse had gone to sleep.

The reproduction is amazing fast too.

Oh dear ... Think I cannot add another fish to my nano already ..hmm guess my only way is to painstakingly remove once I see them ...

Also inspect for eggs. Better to remove the Monti and other Montis and digis to do a through inspection with a magnify glass. Use a brush to remove them before doing a dip. Like Thomas said, they re- produce very fast.

That's why i'm really cautious abt adding new corals without physically inspecting them first before doing a rx dip.
