Injured fin?!!?

[xtcking]

I just got home from work and went to change and see how my little buddy was. Hes just chilling in the corner. and looking in from the top, hes only using one of his fins (by his gills) the left one.. I cant tell if its pressed up against his body or just gone..... hes using the one on the other side like normal. but the left one I cant see. and hes normally really happy and active when I come in the room. not just sitting in the corner! tempurature is normal, actually a degree above what it normally is this time of day. nothing in his tank has been changed in the past 48 hours. Im actually about to do a 100% change today but....

whats wrong with him?

Do you think you can post a pick so we dont start jumping to conclusions? It will help us rule out different problems
