View Full Version : My Finger Leather Coral is not opening

Iím really worried because my Finger Leather(2 years old) is not opening. About one month my nitrate is a little high (20 - 25 ppm), but my others coral still are going well. The finger leather is supposed to accept high nitrate level, and Iím thinking that this coral got a king of bacteria. Iím including a picture where you can see the coral. Do you think that the problem is bacteria o nitrate?

NOTE: actually Iím doing some actions to reduce the nitrate.

IMO thats what Leathers do from time to time.

How long has it been closed up?

This coral has been 3 weeks closed up, but it was slowlly branch by branch

It should bounce back in another week or so if your water prams are good mine did that when my nitrates got high 40 ppm and when it came back slowly branch by branch it started growing like crazy now its over double in size anyway you should be fine.

The coral is getting smaller, I'm not sure that it will suvivor.

is it to close to another coral?

not, only this one.

Post all your parameters.

Something is wrong with your water if its dying.

leathers closing for a week or more is not an unreasonable thing, unless it is actually decaying, it is not dead. Sometimes when mine are closed, I spray them off with a turkey baster and they open up, sometimes not. They can look significantly smaller when they 'push' fluid out. Usually when this happens with mine, they come back with a vengence when they open back up :)

I second the post water parameters just in case though.

My finger leather once went almost a month before reopening, but when it did it was the best it had looked in a while. It's part of the natural growth process where it will almost "shed." However, if it becomes detached from the liverock or starts to decay, they you may have a problem. Good luck

Has there been a change in the amount of current/flow that it's getting?

Manuel Martinez

The water current has not changed, the only thing that has change is the nitrate from 5 ppm to 20-25 ppm, but finger leather suppost to accept high nitrate level.

well well well, the finger leather still is closed, my nitrate got down from 25 to 10 ppm. At least the coral is well attach to the rock, but I don't know were the problem is. ???

NOTE: the others corals are going well.

Any Idea ??

mine closes like that too, one thing is if you dont have enough current on it it developes an ever growing coat of bateria that restricts resperation of the coral, suffocating it basicly, try putting it in an area of higher current and see how it does

Really this coral is locate in an area of very high current. Actually I'm using a Koralia 4, and my tank is only 75 Gls.

The tip of the finger is getting blank

maybe is a kind of bacteria?

What are you using to check your salinity? Maybe it has crept up a little and the coral is not happy. Make sure your using a refractometer for more accurate salinity readings.

These are my tank parameter:

Salinity 1.026
Calc 420
Nitrate 10 PPM
Nitrite 0
Phos 0

The coral still is closed. Honestly I don't know what's going on.

My Finger Leather still is closed and getting small for about 3 month. I have been trying different and nothing has changed.

Please does anyone have an idea?

I'd like to know how this works out. I have a cabbage leather closed for about a month and the finger isn't opening up as often either. Other corals, kenya tree, xenia, brain, candy cane, frogspawn are doing fine.

I really wouldn't worry about leathers much they are really really hardy i had one start decaying and it bounced back ...
try and frag a finger and do an iodine dip and see how the frag acts compared to the mother if you feel like doing something drastic

12/30/2009, 11:23 PM
No +1 sometimes leathers just do that, but I did loose one out of the blue one time, personally I wasn't too heartbroken because I was making the transition to SPS.

But I would say +1 on the iodine dip if you really think something has infected it.
1+ on the increased current, leathers are subjected to some (randomized) current patterns.

12/30/2009, 11:33 PM
Changes in lighting will set them off too. Are your bulbs old and shifting spectrum? I agree with not worrying unless there is decay- in which case cut off the decay back to good flesh.

12/27/2010, 10:40 PM
this was about a year ago - so whatever happened to the leather? did it recover? or was there an underlying problem?

one korallia 4 isnt much they are not the best for movement
