Is this sponge dying (pic)?

It has all those white tips...

[SDguy]

Yes, the white tips are dead tissue. I would cut these off with a clean, sharp blade, scissors, whatever. Just do not take it out of the water to do so. Always keep it completely submerged.

Good luck with it.

Do you think its a light problem, too much or not enough?

[SDguy]

Most sponges don't require light. And the light is only detrimental if it causes nuisance algae to grow on the sponge.

Are you feeding it..... aren't sponges heavy filter feeders?

[Mikro]

Yes I feed it Phyto Feast

Ok.....I think that type of sponge also prefers very good flow and low light.
