Hi, I have had Copepods(2 antennas and tail, last picture) in my tank since I bought it 7 months ago. In the recent weeks I have noticed another most likely pod, that's all over the glass. They can be different sizes, max 0.5 mm. The bigger they get the more black they seem to have on their bodies. There is also a variant that looks like 2 connected bodies.
What can this be? Thanks for the help!
