Coral bleaching help

Sheripie · Oct 15, 2020

My friend's coral is bleaching over 3 days now. He is wondering whether he should cut non bleaching area off or leave it...

Anyone?

If he has a frag tank that is not experiencing the same then yes that would be a good idea. But if not then really finding the problem so it doesn't continue would be ideal.

Has there been any swings in any parameters including temp?

All of his other sps in the same tank are doing fine just this one coral... He doesnt speak English so I had to be the one asking
His temp shouldn't swing since his tank in air conditioning room 24/7. I'll tell him just frag it

Are they bleaching? Or experiencing tissue necrosis? Are they just loosing color or is the tissue actually falling off. Looks like stn to me

One coral randomly bleaching is very common,just cut it 1/4” above dead part, probably won’t save it but try it

You are referring to tissue necrosis not bleaching.

Looks like it loosing tissue on the bottom
if all other corals are fine and levels are stable I wouldn’t worry about , one random sps dying is very common

Yea I see the necrosis. I was just saying what his coral is experience is necrosis not bleaching. Two different things.

Cut it where it isn’t bleaching and glue the stick to a new frag. If his other sps are doing fine than he shouldn’t have to worry too much. This can happen ramdomly once in a while. I had 2 of the same acros in the same tank and one manage to stn and the other is growing like weed. Still can’t figure it out.

Just so everyone is clear on the biology...necrosis follows bleaching, they are very much connected.

They defintly do. Not always. It’s not uncommon to have a bleached sps

I defintly agree. Not uncommon to have a bleached coral recover and never show signs of necrosis though. The way you handle each one is different though. I would never cut a bleached sps, if I don’t have to. it’s already stressed enough. I would defintly cut one experiencing necrosis.

Although I have been very successful with dips of amoxicillin and full tank treatments of witch hazel and beneficial bacteria to stop necrosis with Pugh cutting .
