Ok, I've had this carpet nem for 2 months now. Since being added to my tank it has doubled in size. I woke up today and it was doing this. I'm still iffy on all of my nem knowledge, but it looks like it is throwing up its guts?
That is what I thought it was doing...but I didn't feed it anything. Infact, I have only fed it once. I only feed mysis, to my fish and my anemones, which are quite small. Wonder what he ate...all fish are accounted for and I only have snails and some hermits in the tank.
