this weird sponge is getting worse. totally crowding out the zoos and now it's spread to a couple different rocks in my tank.

air doesn't kill it and it seems to enjoy the light.
help!
 
Rock Beauty Angelfish and Regal Angelfish. There are also starfish and nudis that eat sponges too, can't remember the names now.
 
i got same stuff but white in my tank dert i just put in a orange linkia to see if it gets rid of it, nudibranches get sucked up in overflows and power heads.
 
You might run into a problem with adding things that eat sponge. Remember, just because they will eat sponge, does not mean they eat all types of sponges.
 
Not all sponges die when exposed to air.

Deep water sponges will definitely die if exposed but there are types of sponges that are exposed to air every time the tide goes out. Doesn't bother them at all because they are used to it.

Buying critters that feed exclusively on sponges is essentially giving them a death sentence. Once the sponges are gone the critter no longer has food.

The diet of linckia stars is unknown at this time so they may or may not eat them.

Have you tried manual removal?
 
Just take out the rock that has sponge on it, frag off your corals and let the rock die. Remove it before it dominates.

If you can't beat it, get rid of it I guess.
 
so i take the rocks out that the sponge is on.

do i let them sit out in the air for a couple hours and put them back in? will that cause me to have a spike?
or do i need to leave this stuff out for days. will that cause me to have a spike?

how can i frag the zoos that are in the sponge?
do i just cut them off real low?
 
Any time something dies you will have a spike.

The length and severity of the spike depends on how much dies.
 
hmm...
recommendations?

i'm guessing light deprevation or putting it in an extremely high flow zone aren't going to hurt it.

manual removal: i'm sure i can scrub it off the rocks that it's on. but it's infesting my rock of zoos that you see.
i need to take an updated picture. it's a lot lot worse then that now.
 
To my knowledge there are no sponges that require or even like light.

What may appear to be them liking light is probably more them liking the amount of flow where they are currently located.

If it were me I think that I would just try manual removal.
 
I had the same sponges on a rock that was right under a 175 MH

(right under the Tunze)

It went away on it's own within a couple of months or so.
 
If you kill the sponge by drying it out, it will release its toxins and bacteria which will cause a white fungas and infect the mat of zoos on that rock, which could kill them and infect other zoos in your tank, as the bacteria spreads.

I would just take an exacto knife and scrape as much of the sponge off as you can, or peel your zoos off. You wont hurt the polyps! good luck
 
peel off my zoes? do i just pull them off? or do i cut them off as low as i can? how do i reattach them?

I would remove the rock and put it in a bowl of tank water . Then use something to clean the area you want to clean off . I use the new power scubber you see on TV for those hard stains . It is water proof and battery opperated and comes with 4 brush heads works real well for those hard to reach places . Just make sure you remove the rock first so you don't spread it all over your tank.
