yellow spots on leather coral

**Hpimichael02** · 02-26-2012, 02:27 PM

hey guys,

i came home last night and noticed that i see one area on my leather that had a yellow spot like a powder substance, with a slight gray area around this spot. could the coral be shedding its skin? alson it does fell slimey all over. i have moved it to a high flow area. what could this be ? a diease? would coral dip help ?

That doesn't sound like normal shedding to me. When my long tentical toadstool leather sheds it's skin it gets what looks like a waxy film on it for a few days and then it's gone

I does sound a little like alleopathy (spelling?) which is casused when one coral stings another.

If you have other corals near it, I would suggest looking into that as a possible cause

okay im glad i moved it but the only things near it were tiny fragments of palythoa's and a trumpet coral frag(2 heads) and acans that are in the lower corner aroun 8 inches away. all my agressive corals are on the other side of tank. im goonna throw him into my quarentine with fresh tank water to see if it will get better in their.

I would run some carbom for a while (a week or so) just in case there are some defensive coral toxins in the water.

it could be the high nitrates as well, stressing the coral to the point of necrosis.

When corals aren't doing well, IME, its because the water is not meeting the requirements. I've just done a huge adjustment to my tank in order to improve coral health, most of it water balancing.

well my nitrates did reach 20ppm a couple days ago with a mad algae outbreak, since then i have done 3 water changes of 10% each. thanks for the advcie guys.

could chloramines cause this also ?

if it was something like chloramines I think you'd see it effecting other corals as well... like Cliff and sheamuria have suggested run carbon to get any possible toxins out and then try and maintain your water better... you trate spike could have stressed some corals causing them to release toxins which effect some corals more so than others
