Anybody keep freshwater sponges?

Very interested in these inverts but not much info or people keeping them.

Of course, you don't see these often because they are seldom found. Most sponges are found in SW rather than FW. Also, they prefer established tanks due to their filter feeding habits. This isn't something you want to keep for a long time and that includes clams and mussels as well.
