Re: Freshwater Sponges (Was ZEBRA MUSSELS A BAD THING :( )
Actually, freshwater sponges are quite similar to marine species. Both
are sedentary filter feeders. In order to be compatible with fw sponges,
a waterway must have slow current without spring ice scouring. They
look like a bit of foam rubber on a stick or other fixed surface and are
the home of an aquatic insect that is dependent upon them for food,
although I can't remember the name of the insect at the moment.
Suggest that a captive situation would have just a slight current and
limited or no filtration to allow enough food to be available to the
sponges. Also would not want excessive lighting to avoid algae clogging
the sponges.
I found them in a short section of a stream emptying a warmwater pond in
Marshfield, VT. Very limited velocity and good overhead cover, very
little algal growth, lots of sand and cobble rock substrate.
