I decided to take down my frag tank and forgot about these sponges that I had in there. I like them alot but affraid to put them in my main tank. I'm affraid that they might take over the corals as you can see from the pics. Do they need light to survive. Will it be safe to keep them in the sump. I would like to keep growing them.
