Sponges - are dead spots deadly?

[non-photosynt]

Are dead white spots on the sponge:

1) lead to the sponge death,

2) just be as they are, no harm to the other tissue,

3) will regenerate?

 

General articles and logical conclusions favor an option 1.

Any personal experiences or links to them?

Thanks.

sad to say, i think its 1)

 

has it been exposed to air?

Not my presence.

I wonder if you could frag a healthy the dead spots off of it and save the rest...

That's beautiful. Frag it and sell a piece to me please!

Of course, you would have to frag it in the tank or get it out of the tank without exposing it to air...

Thanks, I'll try to find more information on probability of success of sponge fragging.

Take a pair of soft coral fragging scissors and cut the dead piece off of the sponge.

 

Do not remove it from the water and it will recover just fine.

Very fast progress with dieing: fraged it Nov22, just cut off under water any dead tissue, whatever left - placed in separate pico tank.

Next day - new die-off, cut again, added carbon, hours later - more die-off, cut again, and next day even more, last time cut, next morning - all dead.

Two and a half days after fraging, less than week after acquisition.

 

There was aragonite sand inside the two long passages inside the sponge. I was specifically careful when did partial water change in the main tank, but clearly not enough. May be initially the sponge should be placed high on the rock.

 

Lesson learned.

 

Orange sponges were in the same conditions without any problems, ball sponge has large openings too.
