Ah ok I've never tried red bc I was once told its sponge based more for angles. That seemed a bit odd so I figured I'd inquire. I'll try some red today
If you have shrimp it's OK if they eat a little of it (they also love nori). Just don't let them over do it on the red because of the high Iodine content.
I've gotten that. I get a mixed pack of Rods and ther is always a clump of dried sea wee along with the processed sheets. I like the sheets better they don't fall apart as fast.
