I have four frags of this bright yellow sponge. This stuff is growing in a couple spots on my rocks and it adds really nice bright color.
Must feed food appropriate for filter feeders (I use freeze dried cyclopeeze). It's totally non-photosynthetic. In fact, these pieces grew in my completely dark sump!
