Hi guys, this is my first tank for a couple of years so I'm a little out of practice. I set it up a couple of months ago and added livestock last week. Today I noticed two of these little round worm-like creatures in my aquarium, right down at the substrate. They mostly stay completely still, though I caught one moving a little like an amoeba or something. Google's best guess seems to be planaria, but these guys are very round and don't have that angular head. I've taken a couple photos with my phone's macro lens, mind they're on sand substate and the big round thing is a single grain of fluval stratum. They're a little grainy but they've got a white-ish opaque body and four little white 'dots' that seem to be in the same pattern for both. If they're not going to hurt any of my fish or shrimp I'm happy to let them chill, just curious!
For reference, my tank is a 57l aquanano 40 stocked with 9 kubotai rasboras, 5 amano shrimp and about 10 RCS. I got my plants kind of all over the place, from various different retailers.
