Bent Back!

[magicd]

Hey guys,

One of my Zebra Danio had a bent back and it was swimming really weird, and it also looked like it was trying to scratch its tummy on the plastic pot i have in the tank. It has passed away already...i left it in the emergency tank over night though. I have 3 other Zebras and they seem to be doing ok but one of them hides in the back.

Can anyone tell me what is the cause? There wasnt any spots or anything so i dont think its itch.

Thanks

Danios can get bent spines as they get older take a look at this link.

When a zebra danio is nearing the end of its typically two year lifespan, there will be a moderate to severe curvature of the spine. This is occasionally confused with fish tuberculosis, a disease that can be passed on to humans. If your fish are young and exhibit this particular trait, then you should take the highest precaution in diagnosing the cause. Remember though that stress will often be responsible for the reduction of the life of a fish, and that a zebra danio that experienced a high level of stress as an immature fish may have its life expectance reduced to no more than nine months. Zebra danios are not prone to any particular disease, and because of their active nature they are seldom affected by ich, due to the fact that they will brush off the fungus in their everyday activity of passing by stones or plants in your tank. One thing to look out for is gill flukes. If you spot your zebra danios rubbing themselves along the substrate of your tank, then you will probably need to medicate the tank with an anti parasitic medication.
