I have never seen this worm in the past it is not Planaria or a leach.
I picked out 2 of them with tweezers swimming in the tank in the past 2 days, never seen them on the glass or substrate. I would say ½ inch long the top half it is thinker and the bottom half thin.
What could it be?
Raven I appreciate your help, When I see them I grab tweezers and pull them out they are too small to take a photo with the phone and don’t keep my SLR by my tank in fear that my 3 year old son might stick it in the water. He did that with my phone.
I tell ya, I've got on Olloclip for my Iphone that does a great job on macro pics...sometimes it's the only way I can identify bugs! I think they are fairly cheap if you've got a phone they will work with. I don't keep my DSLR near my tanks either I'm accident prone and have a child too
Flat white worms I think more common in tanks are rhabdacoela and planaria. Skinny wiggly round worms can be nematodes, detritus worms, and some others (can't recall off the top of my head).
Looks a little like an earthworm, doesnt it.. It's an annelid which makes it a Detritus Worm. If you use a strong magnifier and some good light, you should be able to see body segments like an earthworm and see two hairs growing from each segment.
