First it was Tall now becoming limp

Hiya there, brudders & Sistas

Need assistance on how to maintain a blue sponge, my button and finger mushrooms seem thriving but it seems the bluey is kinder going limp...

Some parts of it seems to be growing thin lines but most stems seems to get smaller, there are holes in the middle, first they become white and than start having holes in it.

hope some one here can shed light on the problem?

Anyone Help???

If it's wasting away slowly most probably it's starving to death. Get a glass bottle, invert it over the sponge, and squirt phytoplankton under the bottle for it to feed. Or alternatively dose phytoplankton to the whole tank if your skimmer can cope.
