hmmm....wonder if its a small stormilla snail. I have a bunch that hitchhiked in....If you can see the top they have a tiny shell almost like a finger nail. If it is its a good guy...
tested nitrites and nitrates a little bit ago and the nitrates have jumped to 30ppm...should I start seeing a fall in nitrites soon? they still read 5ppm or higher
These look a little like some isopods that I had in my big tank. I never got a proper ID on them, but they never bothered anything so I didn't worry about them.
