Hello everyone, I'm new to the hobby and over the course of the pandemic, I became an owner of 8 tanks and 5 buckets. I have animals from shrimp to a baby arowana.

But today, I had a very curious discovery in my Taiwan bee shrimp tank. In this tank are 6 cardinias, 1 nerite snail, a few black worms doing their best mini Dune sandworm impression every night, and a couple dozen bladder snails. My discovery of these .. things really perplexes me. Nothing I have in that tank can produce something this big. This leads me to believe it came in on some plants I bought. My most recent addition was some subsswassertang I got off of EBAY.
The images below are from a USB microscope. I thought it was moving before but it could have been the snails underneath it. Unfortunately, I wasn't able to get them out without applying the right pressure to my tweezers and white stuff came out. The more I look at it the more it looks like an egg pod. I am at a loss because nothing in that tank could possibly produce something this big besides the nerite snail. It's a good 1/2 CM in size. Does anyone know what these are? Most of the tank is covered by a weed carpet and I'm afraid there are more and these things will become some kind of isopod wreaking havoc in my tank. Any insight is appreciated. Thanks!

To me that looks like some kind of insect pupa, which would mean it's probably dead unless it's from some kind of water bug. I don't know, but it's interesting. I would take it out and put it in something else just to be safe, but it's probably harmless.
