Problem with acroporas

[PedroMurcia]

Hello, for almost two months ago, my acroporas presents a problem I know. First clear spots in the tissue appear, from base to tip. After these spots cover the entire tissue, leaving the acropora completely cream-brown color, not growth, not polyps extension.
STN episodes also observed only in dark areas, brown the bottom tissue has disappeared in almost all.
Salinity: 1024-1025.
kh: 7-7.5.
NO3: 2ppm.
PO4: 0.02.
Temp: 25 ° C.
In December I did a triton, the entire analysis in green.
See if anyone knows that this can be, thanks.

Alot of bites, probably AEFW

I agree, those look like bites and eggs. Only way to know for sure is to dip and see if any flatworms peel off.

I would dip immediately and if you've traded corals with anyone recently I would give them a heads up.

There is no doubt those are aefw bites and eggs. There is plenty of infp here on how to fight them.

Hello, last week I started the battle. First introduced a six-line wrasse and synchiropus, but if they should do something, it would be too slow, and acroporas were already very bad.
Wednesday decided to take the first bathroom with levamisole, 1 ml / L (product concentration is 75mg / ml).
By introducing the pieces in containers brittle stars, asterinas, worms ... died almost instantly.
About an hour and a half later, the first flatworms began to part. Until then they are completely transparent, before they took a translucent shade, some were killed and many others living or with spasms.
Three hours later, the amount of flatworms was huge, in the picture you can see, most of them dead, though others showed good condition, even one was attached to the bottle.
The water used was a water change, and this was the same that use (and cold) to rinse the pieces.
Today, some are beginning to show some signs of improvement, not polyps, but yes in color, but very slowly. Although fairly because you could see in the pictures that had very big infestation.
I will continue periodically with baths for at least a month. Besides network fight red bugs that do not know where they have come to my montiporas, this is crazy.

I wanted to thank you for your quick and accurate response, and especially thank my girlfriend(I have a biologist at home) who helps me with the identification and especially encourages me and supported me, without she surely would have thrown in the towel :love2Si lees esto no te rias de mi ingles jajaja).

I will keep you informed.

After the battle, I think they have disappeared.
Perform a weekly bath (every Wednesday) with levamisole, 3 weeks and a final bath with Coral Rx. At the same time, in one of the urns I introduced a intestinalis and 3 Lysmatas wundermani and in the other a durbanensis Rhynchocinetes and picturatus.
All have done their job, no trace of eggs or worms.
I have observed that damaged tissues eventually decompose, and this affects the acroporas different way. Species like millepora, echinata, tenuis, loripes, granulosa ... eventually die, they are not able to slow the loss of tissue. But others like nana, torturous, microclados, validates, formosa ... lose tissue, especially the areas of shadow, but endure the rest and recover.
Another detail that I have observed and had no knowledge that they can eat stony corals. They finished with a friend Montiporas dish. We did not know why they died, and bathe them in rx coral, lots of flatworms of the bottom of the montiporas came off.

Thanks for the help now to rebuild everything and hope not to see them again.

Keep an eye on the coral for a while since it may take several months to break their cycle. The eggs are not killed in the dip. They must be scraped off the coral manually.

 

[PedroMurcia]

There are no eggs, at least visible. But if I think that at least for a while, these worms are hidden, part of the fauna of the aquarium, but in a very small quantity, there will always be predators, to prevent resurface.

Your second picture from the left appears to show tons of eggs. They usually lay them on the bare underside of coral or very near the base of the coral. They dont hide them in other areas of the tank. If you removed them during your dip process then you may be ok.

 

[PedroMurcia]

Yes, I know. That acropora suffered bath, manual cleaning and subsequently by Rhynchocinetes and intestinalis. Currently I see no eggs or symptoms in which they have saved. They have since recovered tissue and are beginning to have growth.

 

[PedroMurcia]

Just as I thought, someone is alive. Today there has appeared a acropora valida with signals. In the aquarium where only is the intestinalis, introduce one Rhynchocinetes, in another aquarium made a good cleaning and symptoms have not returned.
