I don't have a camera, sorry. but it looks like a 2 inch spiny white sort of translucent sea cucumber. It has sort of a crown on the end, and it has split into TWO!!! Then, as I was looking around in my tank, I noticed tons of little white things on my glass, maybe isopods, and so I brushed them off. Now, a coupke weeks later the thing is bigger and there are like ten centimeter long ones on the back of my PH. It is freaking me out. They are definitely not pods either. They have like a crown on one and and they are prickly and spiny. Any ideas?
