Bend in the spine of my fish...?

[Ermasdaughter]

Hi All! Hope all is well!!

Spring is around the corner and things here in Barcelona are starting to warm up. Our day temps are around 55-60 and as such my fish have started coming to the surface again. I noticed one has a bend in its spine near the tail that it didn't have in the fall. It seems fine in that it's swimming around with the other fish..

I've heard it may be a nitrogen problem? Is that correct? Anything that can be done or is the fish dying?

Any advice would be most appreciated.

Thank you!
Michelle

I don't have experience specifically with koi or comets on this issue, but I have seen it show up in aquarium fish (especially guppies) where there is simply too much inbreeding. Sometimes they will lead a full life along with the other fish in the tank, and sometimes they just can't survive. The curvature of the spine causes them to have to work extra hard to get food and avoid predators. Regardless, the best you can do is check your water conditions and try to correct any problems you find. After that, the fish's survival may simply be up to mother nature.

we dont know your situation, that said...it could possibly be Scoliosis
Electrocution by lightning or faulty electrical equipment (e.g. submersible pumps) is documented to cause spinal trauma in fish. Affected koi display kinked backs, can swim erratically, and display buoyancy problems. Scoliosis can result from vitamin C or tryptophan deficiency. Other causes include spinal trauma, muscle damage, organophosphate toxicity, and arsenic exposure (e.g. pressure treated lumber).

This is caused by electrocution. Check your wiring!

@InsideSeven Hello and welcome. This is a very old thread and I don’t think the OP is around any more.

JUST IN CASE KEEP YOURSELF CLEAR OF THE WATER
