I was given an acro to see how it would do in my tank. I haven't seen anything bad with it yet but I noticed the bottom looks bleached. Is this normal? I have heard of necrosis (I think that's what it's called. Where you have to cut of the part of the coral thats still alive..) but I'm new at this. My Birdsnest and monti are doing great.
It's almost impossible to say what's happening to it except it is bleaching from the bottom up. There really isn't a definite answer on exactly what causes coral necrosis.
RTN = rapid tissue necrosis
STN = slow tissue necrosis
It's definitely bleaching though? I saw it this morning and the polyps were out on the more colorful parts. If it does have necrosis, slow or fast, should I frag it? I really like the coral and don't want it to die..
I just looked at it and one of the whiter parts is getting a little color back. It was pure white and had a very small spot of color at the tip. It is now more of the brown/ red than white. Does this mean it was just because of the acclimation? Sorry for double posting so many times, I don't usually do that.
The acro frag I got looked 'bleached' when I put it in my tank in the exact same place as yours, found out it was just encrusting the frag disk it was on.. it was just new growth.. a week or so later it started getting the color of the rest of the frag.. maybe its just growing?
