well im just waiting for the octo to come in next week... in the mean time my tank has been set up and cycling for 2 months now and is waiting for the resident...

to my question

i know that sponges are great for absorbing nitrates etc. and i have access to lots of bright reds and orange finger sponges along with tunicates etc. and was wondering if these were goin to be shredded by the octo or if i could use them as supplemental nitrate removal and toss them before they crap out on me and nuke out the tank... dont know if anyone has tried this before but if anyone has any input i would love to hear it

Sponges and tunicates are difficult to keep successfully and yes, your octo may move, damage or shred them.

Plus they occasionally have hydroids growing through the matrix and they sting!
