I know that sponges don't love light, but what exactly is their story?

Do they need light but just very little and maybe indirect? Or do they need darkness? Can they for instance be attached under a ledge etc or is that not dark enought for them?

Cheers

As i understand it, they grow in total darkness and heavily shaded areas, so i would aim for as dark/shaded as poss, certainly all the "hitchiker" sponges in my tank grew in the dark.

Yeah the ones I had starts to grow beautifully and then just dies. Not sure why. They grew in shade but not exactly dark. That's why I was wondering about the light issue.

Hi Galibore - I have sponges that seems to thrive in my tank. They are hitchhiker sponges that starts to grow - seemingly "out of nowhere". They do not take over though - they grow beautifully, but stay small'ish... BUT, one thing though - they do seem to favor darker spots UNDER live rock, in my tank...

Galibore, check these "sponges" they are living in my substrate so, no chance of light.

Geez that's interesting. One would think they not getting much to feed on in the substrate. Let alone light.

The funny thing is - sponges sometimes turn up at the funniest of places sometimes. They grow on the back of my power-heads, in my sump - on the glass - below my substrate - below my live rock....
