You are right Aaron. I am generalizing and basing my statement off of my experience. I would like to point out in the Calfo quote "They are unique among Poriferans in that they like very high light". This would lead me to believe that most don't. I also have several of the same species of sponges growing in my display in high flow areas and also in my cryptic fuge. I added the sponges to the cryptic tank. They did not come form the LR.
You would obviously know better on the subject of the blue sponge being discussed. I am not arguing that what I am saying applies to that species. I am just generalizing IME.
