Recently set up a 10g as a cherry shrimp-only tank, water conditions are pretty pristine in there because of the sensitivity of the shrimp.
Anyways, it's been set up about 2 weeks and just in the last couple of days I've noticed some small planaria in there, as well as these translucent, football-shaped creatures. They are very fast, they can swim quite readily through the water column or else they bound around on the substrate with seemingly quite a lot of energy.
Most of them are very tiny (the size of a grain of sand maybe), but one or two seem to be full "adult sized," as the picture shows. The main part of the pic shows one up next to one of those standard hanging metal thermometers, so it gives you a sense of size (maybe a few mm long), with the inset simply being a more focused image of the thing.
Anyone have an ID on it? Thanks in advance!
