My first thought would be Brooklynella or Marine Velvet, but looks more like Brook to me.
If that's what it is, it moves fast and kills quick! Only way to treat is with Formalin. If you don't have access to Formalin you can also use Quick Cure. Naturally, this has to be done in either a QT or a bucket with airstone because you can't use either Formalin or Quick Cure in your DT.
Also, all other fish will have to be removed and treated even though they may not exhibit signs as of right now.
