?RTN? help!

[springeri]

All,

I believe the coral pictured is some kind of a tort. I could be wrong. If anyone could ID that would be helpfull.

Second picture shows some kind of skin recession. I believe this has been going on for quite some time, but I just noticed it in the last couple of weeks.

As you can see the living part of the coral is very healthy. But there are obvious sign of poor health at the skin recession area.

Should I frag it out, or leave it to heal. Will it heal? please advise if you've dealt with this condition.

I plan to frag it to salvage what i could. Please advise

parameters:
temp: 77-78
Phosphate: 0
Calcium: 400-440
Mg: ???
Alkalinity 10.5

thanks

When in doubt frag it out save what you can.

thans Brewen,

I'm planning to frag the tort out tonight. I thinks its a myagi tort from some website i bumped into.

But is this RTN? Regardless the case, I think it's going to get worse if I leave it alone. so yeah it's FRAG time I guess.

might be STN...RTN works pretty fast, more like hours.

 

[springeri]

yeah this wasn't a couple of hours... it's been weeks like this. the tissue doesn't receed to where you could tell from day to day.

It takes much longer than that.

What is STN? I tried to search but the search isn't working right now.

thanks.

It could be the AEFW. You can try to turkey blast the bottom part of the colony to see any flatworm falling off.

Loc,

I've checked it before, and there are no flatworms on the colony or awhere else in the tank...

STN is slow tissue necrosis

RTN is Rapid tissue necrosis.

RTN happens within hours. You leave to go to dinner, come back and the coral is completely white and all tissue is gone.

I hate to even mention these but its could be

RTN works that fast, as in hours. I thought it would be over a couple of days. I had a mille have tissue just fall off, but the whole colony was gone after a week, not during dinner.

cr, maybe you had MTN

Mille Tissue Necrosis.

You may already know this but you can't really tell if you have the flatworms with an in-tank inspection. They are so hard to spot even with magnification.

Do you normally test Mg? Depending on your salt mix it could be very low or very high.

Slow tissue loss can also be caused by lack of flow in the center of the colony. If that's suspect I'd try adding flow to that area instead of moving the coral. If you move it that could just add more stress to an already weakened coral.

From the picture it's not easy to tell what's happening. Light and flow issues start with real light colored tissue that may lead to thin tissue which then dies. Flatworms on the other hand you can see were the flatworm has eaten tissue and there will be a hard line between healthy tissue and damaged tissue or skeleton. Flatworm damage looks a lot like someone took a bite out of a sandwich.

So is a yay for me to go ahead and frag it and save what's left?

 

[GTR]

You gotta make that call. Long distance diagnosis is difficult to impossible.

thanks....

This is going to suck! It was just starting to color up really nicely too.

Oh well I'll have a bunch of little Baby torts. And if everything heals properely I could always trade or sell if anyone is interested at the point in time. (ONly if the frags are healthy that is =)

thanks everyone for the great feedback. I'll probably take the safe way out and frag it in the next couple of days.
