Sponge questions

I picked up this the other day.. Lighting needs?
Had one before but color soon faded.. was in low light--low flow tank

They don't need any light and they like medium indirect flow from all different directions so no debris gets built up and clog them.

I really apprish.. the feed back!!
They are growing on direct sunlight side, high in water coluum but not on the shaded side.. I just was thinking it had something to do with light..
