Somethjng eating my zoas

[CaptainJugz]

I had the same trouble with the same xact breed you are having trouble with. They are very particular about placement and flow. Mine slowly vanished while others beside them flourished. Good luck! Second photo is what's left of the greenies....

Always remember that zoas when dying can let off toxins causing water to stress for few hours the stars will for sure only be there for the dead tissue the nudi is so so hard to spot and some barely to be seen at all there so small coral rx would bennifit you 100%... What flow do they have....? What lights do you run what are your water par how low in the tank are they? I know a guy who specialises in zoas which i will more than likely see over the weekend

Still waiting for that coralRX... The flow is moderate, I'm running 250w MH 20k with 4 t5's and they are place mid to low in the tank. Water par.... Ph 8.1, ammonia 0, nitrite 0, nitrate < 5, calcium 450-480, kh 140ppm, copper 0.

My bet it is a nudi, I can't see how else they would jus start dying off.

So I got coral rx pro and used as directed. Bunch of crap came off and a bunch of bristle starfish. After about four days went by I still noticed some polyps still shriveling up with a Mucous layer around it. Looks as if its being eating inside out or the life sucked out of it.

I've been told maybe its sea spiders? But wouldn't coralRX take care of these pests.

No way on spiders...I'd be more thinking of a fungus.

I would still think its nudis you need to regularly treat untill pest is under control once will get alot of them gone yes but nudis lay eggs rapidly when thriving off your zoas they are so hard to spot when i had problems with mine i had to wear gloves and when dipping in coral rx i had to gently rub the small eggs off the zoas 'foot'

In my experience nudis take to what ever color zoas they are eating. When your zoas are closed, just look for what looks to be a zoa polyp tentacle. I noticed mine on my dragon eyes when they were all closed and what seem to be like two polyp tentacles. I check again in 5 mins and they were somewhere else. As soon as i tried to siphon him he turned in to a ball and took to the currents and float away but i got his ***. I then dipped the colony

It's not nudibranchs or sea spiders. Both would be dead after a dip and only the eggs would remain.

I gotta say I havent had much luck with zooa's. They start off just fine and then seem to just disappear one polyp at a time. I know it's not an answer but some people just cant keep zoo's. lol If you have dipped then it shouldnt be nudi's like Mr. X stated. Id there anything that could be munching on them like a fish?

 

[mr_X]

Sometimes they get infected with a sort of fungus, like stated above. Possibly an iodine dip may help that, but again, you would have seen nudibranchs or spiders in the RX dip if you had them.
