Axolotl Spasms

[Haileyasfar]

My axolotls keeps having what looks like spasms or fits while floating in the water , they rapidly shake and swim around the tank . Is this something I should be concerned about and if so what is the cause and how can I fix it ?

Have you done any water changes that may have triggered this? Can you test your water parameters?
