Recently my clam bed has been attacked by two types of sponges. I've heard that sponge growth is a sign of a healthy tank? But this is getting crazy. I was wondering if anyone else has any experiences they can share?
I have three clams up in the bed. They are absolutely thriving and open up beautifully every day. There is a smaller clam, a maxima that has recently become shaded by one of the two croceas. I went to move the clam the other day and noticed that it wasn't attached at it's foot, but all three were incased together in a thick white sponge. I didn't realize this because they open up so fully I hardly ever see the shell and when I do,..... it looks normal? Good....Bad??!
And right next to the clam bed in a slightly more shaded area under an over hang is a spot I keep about 5 or so Florida Ricordea. Slowly over about the last month or more, I've notice this area becoming overgrown with a similar sponge but more peachy or pink in color. There only appears to be one ric a smaller one that is effected by it. All other corals seem just fine.
So I don't know, I've never experienced this type of sponge growth. Should I let it go on? Or should I try to groom it and propogate it?
