I need some advice/help. I was looking closely at my fish when I noticed little white specs all over my back glass. I thought they were the tube worms, but I looked closer and I could see them moving. Im assuming they are tiny pods, about the size of a grain of sand. I have bigger pods that come out at night, maybe about a dozen ive seen, but there seems to be hundreds of little creatures on the back of my glass. Any advice? They are definitely tiny and they are moving for sure. Could it be from the growing of chaeto in my sump, maybe some pods colonized the chaeto and some got through my return pump? Any information is appreciated. Im ok with a few pods, but i dont want hundreds of them. (if thats what they are)
