SPS Bleaching


Reaction score
Ok so I have a 12g SPS nano. I have SPS growing into each other. It will have to be that way until I find a bigger tank.

My observation has been that the SPS touching will bleach in only the spots that are touching. So I thought that's how it would always be.

I've never seen an SPS bleach within 24 hours, but I've always heard about it happening. I come home to find this is the case with a monti digi and another stick is growing into it. The other "stick" may be an acropora. The acropora is fine.

So I assume the other stick bleached my monti. What do you think?
I do have a few more softie frags in my tank than normal. Did a recent thermos swap and I couldn't put the frags in the nudi infested tank.
montipora is a "weak" coral, so the acro could certainly zap it. when you say bleach, do you mean RTN (rapid tissue necrosis)? Is it just a whitye skeleton, or a pale version of its previous self?
This Article may offer some insight

sounds like they may be stressed from competition
It's a white skeleton- no polyps will ever come out again. It's gone.

I do have a much larger frag of this coral about 2 inches to the right, and then a few more frags in the sand bed and they are all fine. All other corals look good too.

Article has been read- thanks!
yup got attacked, if you move it, it will eventually grow over the dead area.
unfortunately its kinda up in the air wether or not the corals will attack eachother, unless there is a master list out there, its trail and error with us :) But I have a piece of green cap and a purple digitada that has grown into the area of it, killed a part it grew over and is going on its way. The cap is fine except in the area of the grow over, and actually now that I look at it its recovered green tissue right up to the digi. Corals are fun! LOL.
yeah, unfortunately tho there was a really nice blue digi that was near a what looked like blasto that sprouted from a rock, things were happy

The other SPS is now bleaching... So I cut it off and they aren't touching anymore. Maybe I can save one of them.
