[LF/WTB] Live sponge or sponge foods
 

I would like to purchase live sponge and tunicates to provide spongivores with good diets.

I have frozen angelfish blends that contain sponge, but are there alternative foods that only contain fronzen or freeze dried sponge? Im not sure how the freeze drying would affect the nutritional value of sponge though.

Has anyone made or purchased something like this?
