birdnest branch bleaching..

[Jakef150]

hi,

I have birdnest pink with mutli branches its approx 4"x5..It has nice color and everything under LED for 8 months with good growth.

2 days ago i spotted birdnest has very small round bleaching (white) on stem (?) and is not from base up, and today its spreading to one branch turns white..

Cal 440
MG 1410
ALK 8-9
1.025
temp 78.5
PH at night 7.9 - daytime 8.3
nitrate 0 (API kit)
phos 0 (hanna checker)

what is possible wrong with it ?

Should I snap one health branch off and frag it as back up if mother is going to dying ?

THANKS!
Jake

not bleaching, sudden tissue necrosis, frag the thing or cut the bottom off and get it stopped or all the tissue will necrose and you will lose the whole colony. now would be the best time. you can try to use iodine on the necrosis area but i dont think that will do much good.

Base is not stn or bleach, its on brach and stem that where it starts spreading.

Ok I'll cut white area off and save others I think I might frag it into 3 or 4

Thanks

I agree with this.Ive seen this lots in mature SPS reef's before HUGE Birdsnets Colonys wither away for no reason.

Frag it & save it.

I have the same problem with my green birds nest..I will cut"frag" it down today!

I once had a colony the size of a cantaloupe and it started doing the same as yours. Because it was my prize show piece colony I didn't want to frag it, so I decided to see if I could battle it. Well, not only did I lose the whole colony, aside from a single branch I managed to save, but it took down 2 other colonies with it. Actually, come to think of it, birdsnests have started RTN events in my tank three times!

IMHO, birdsnests can be a canary in the coal mine indicator. If there is a water quality issue, they can be the first to go and often entirely necrose very quickly. Your stated parameters look good, but I'd keep an eye out for anything else starting to look off or not right.

Agree. My did that when my PO4 started to creep up.

+1, birdsnest always seem to be the first to go. they seem to be more sensitive to changes in the water than other corals or even some test kits.
