Does anyone have or know of long term success with large sponges (barrel, not encrusting)? I know of only one specific species of such sponge that has thrived. It grew like a weed in my tank until it got exposed to air when I moved the tank. I know that the Caribbean sponges are very poor survivors and haven't had much success with them myself. Also, I hardly ever see pics of well established systems with large sponge colonies.
