Bout a week ago I set up a freshwater 10 gallon tank. Yesterday I got a few ghost shrimp and this morning I noticed an extra little guy gliding around in there.
It is a round disc like organism approximately an 8th of an inch in diameter and length. It has a yellow body with clearish white "wings" on either side which just look like an extension of the body and a bunch of clear flagella near it's head and 2 oblong dark spots on either side of it's rear. It is quite cute. I don't know if it is larvae or a parasite or what but I need to know in case he is something that could potentially harm my tank.
It's that blurry yellow spot in front of the ghost shrimp, unfortunately I couldn't get a clear shot of it.
Here it is gliding around in the water. It spends most of its time stuck to the glass or rocks in the corner though.
