Blue sponge shrinking? Would you remove it?

7 months ago it looked like this

This is now...

I know these can be toxic when they die.....so I am wondering if I should remove it or if anyone know what to do to bring it back?

 

[Mandarin66]

are you sure they can be toxin?

 

[koda_dad]

From what I read yes... Anyone else know?

I have not heard that, but I could very well be wrong.

Most sponges need low light but a few species need bright light including the blue ones. Is yours getting enough light?

I have a large blue spomge, similar to yours. I've looked and can't find anything about a toxin being released upon death/dying. Are you adding any sort of phytoplankton to your system? If you keep a super clean tank, that may be the reason for the die off. You may want to add Phyto-Feast of something similar to aid in the available food for filter feeders.

My water has a lot of particles in it and I have sponges and other filter feeders growing all over the place.

Can you move it into a more shaded part of the tank? I dont think they like bright light and it might be receding away from the light.
