Yes, occasionally fish get kinks in their spines but can live quite happily anyway. At the Pet Store I used to work at we recieved a guppy with a kinked spine in one of our shipments, so we put him in the countertop display tank where he lived quite happily for close to a year, when the manager decided it was time to break down the display tank, I brought him home and he lived quite happily in my tank for another year or so
So i have to agree with Zagz, keep an eye on him and if he looks like he's doing alright, i'd leave him be
20gH Planted tank, 5g Planted tank
1 Crested gecko who has a 60g Hex paludarium in the works
2 Dogs, Leo an 11 year old Bichon/poodle mix, and Cody, a 3 year old Poodle.
I enjoy having a zoo to care for!
