RTN?

[mr_X]

i've had this green tipped pocilapora for over a year. i got it as a 1" frag. all of the sudden, the base is dying off, and dying off fast!

what do you think? should i frag it up?

what causes this crap? all the other acros are doing well.

Could be RTN, but that pattern of decay could mean there is something toxic at the base of the coral near the rock. I would personally make a frag or two just in case the whole thing goes, but I think with good circulation, the death will stop at some point.

That almost looks like a Seriatopora to me.

thanks len.
i fragged the whole thing. this colony spread all over the tank anyway.

bleaching near the base is usually an indicator of something bothering it, or poor flow in that area.

ok. but nothing has changed on that side of the tank. it's been sitting there since i started this system and growing well.
no other corals are near it.
the flow has not changed there.

i wish i did have an easier explanation, like the ones you guys are suggesting. :?

My pocci looks just like that and it did the same thing. But mine was so thick that I believe the bottom just didn't get enough light from the rest of the coral above. Still the same way for months and months and the "dying" hasn't spread.

the bleach came out all of the sudden and creeped up quickly. i have since fragged the entire colony. about 85% of the coral was saved.
