is this acro eating flatworm ?

[grimo]

guy's something is eating my acro's im not sure if it's flatworm nor not

My suggestion would be to take one of the corals off. In a clear container filled with your tank water blast it with a strong current where the dead portions are at. Once you feel its been in a strong amount current to see if any pests would come off. Look at the container and see if you see any flatworms. I'm sure you can google and find pictures of a flatworm. Good luck

looks like slow tissue necrosis; basically the coral isn't getting eaten, it's just dying from the base up. Normally bad parameters or parameters swings cause this. My suggestion, test your alk

+1 you would see bite marks on your acros and patches of small green eggs if it were AEFWs.

2nd pic looks like the acro is too close to the cap and is losing the battle. Agree, doesn't really look like aefw

check all your parameters. recent changes, like replaced gfo or switching alk supp schemes... and this is a shot in the dark because i'm going through the same thing now. But check one day when the lights are out but there's daylight and look really really close at the dead white area. And see if you see tiny, tiny white bugs scurrying all over it. I've seen this on mine and haven't determined if that's the cause yet or not but interceptor seems to do the trick.

ok my water is spot on with running a cal reactor im using coral rx not sure if you use that in the us ? what about star fish eating them ?

yeah, was wondering about that- are there ANY corals touching any of what is RTNing?

 

[grimo]

no it's not that it's hitting all but two of my acro's. also i have a frag rack with 9 acro frag's on and there all fine.

any more input ppl

 

[defchild84]

yeah, hopefully the experts chime in, but looks like AEFW. See the lower branch ? follow it to the point where it connects with the other, and at the point you can see the off color brown little guys.... I'm sorry bro!

 

[Whisperer]

Defchild, are you referring to the dark brown spots? I think those are young coralites . I see one FW above the fork on the left.

 

[xcorallusx]

def alk, need to post more info about your tank/what you have done recently.

 

[grimo]

the only change to the tank in the last 2 month's has bean me adding a cal reactor no change in kh in over 5 week's

I would recommend you get a second opinion on all your tests. Test kits go bad all the time. I had STN and couldn't figure it out until I recalibrated my refractometer and to my surprise my salinity was way off.

Dip the coral in Coral RX for a few minutes and you'll see flatworms fall off if that's what's bothering your coral.
