Pest ID Flat Worm?
Today I found a pest in my tank that I have not previously seen before and was wondering if anyone knew what they are and if they are bad for my plants and fish. If they are bad how do I remove them?
The best wat I can describe them is that they look like a snail without a shell. I am guessing that they are some sort of flat worm but I have no idea. It is hard to see in the pics and I will try to post better ones later.
The pest in question is right above the gravel line a little right of center.
Thanks for any help.
