Not enough light for this acan?

[w8_4iT]

I bought this acan (I believe) about 3 weeks ago. I've had it in this spot since. I just noticed it wasn't doing so great on the bottom. Is it going to make it or infect the rest? Thoughts?

All my other corals and fish look great.

I just realized I should've posted this in LPS thread.

While they dont need a lot of light they so best in moderate to intense lighting. Looks like it could be just a closed up polyp so give it some time.

The acan looks fine to me. Be careful with to much light as well. It looks like the bottom of the coral got buried in the sand and that could've been your problem. Typically with acans you want low to medium light and low to medium indirect flow.

Those polyps are really swollen and reaching. This coral looks like it is searching for more light. It otherwise looks nice and healthy. While the do not need a ton, they are going to need more than the Caulestera above it.

Here's an update. The bottom looks much whiter now. Is it dying?

 

[jda]

Yes, that is tissue necrosis.

Yes, that is tissue necrosis.

Should I go ahead and remove it then or is it salvageable?

Do you have a dremel? I'd remove the dying tissue to try to save the rest.

How's the rest of the tank? Parameters?

 

[w8_4iT]

Unfortunately I dont. All other parameters are good and other coral look fine imo. The brain can be brighter but it's not a real concern.

Is the tissue necrosis contagious to other coral in the tank?

Impossible to tell without knowing what is causing it. I do know that people have lost entire tanks of SPS due to bacteria / virus infecting one colony and then spreading to another. I don't know enough coral diseases / pests / etc. to comment on that. If you are really worried, you can always try dipping to see what happens.

Yeah, I've removed it, dipping it now, and will try to QT it alone for a while and maybe it'll get better. Hopefully it didn't catch on other SPS yet. Thanks for the input!

I would dip in an iodine based dip. Not sure what light your using but I honestly don't think the necrosis has to do with your lighting. You'd be surprised at how little light they need and they like to be fed.

It's the Current Orbit Marine IC LED.

Is necrosis highly contagious to other corals?

IMO acans absolutely do not like low nutrients. I don't know if that is your issue, but JME. I always had them on the sandbed so I wouldnt think light is your issue (without knowing your lights).
