Knight Goby Spine Damage

[jonny5]

i cant figure out if this is a physical damage problem or disease but my knight goby is unable to fit strait. His body is always in the shape of a slight curve, kinda like a half circle but not quite to that degree. And when he swims or rests he is unable to swim and rest properly.

He hangs out in the spot between my breeder net (which i just use to house some anacharis)and the tank glass, maybe this is the cause.

I cant find anything on the net about it. If anyone has any info please let me know TY.

now he is just layong on the bottom of a tank (which for a goby is fine) but he is on his side instead of belly/aka ventral side, and he doesnt move. Im going to give him till the end of the week but after then should i euthenize him? I assume the onger he goes the more he wont be able to recover.
