How can i make a smooth tail?

I have 2 Sprites (Dot or Circle) both 50x50 pixel

Sprite1 have drag and drop behavior

when Sprite1 is dragging I Spawn Sprite2 everytick.

When we drag slowly then tail looks good but when we drag fast then it looks into pieces I mean we can see a Single piece of sprite of the tail which i want to hide

How can i do this? to make it more smooth.
