A couple of months ago one of my banded kokopu devoloped a bent spine, one day it appeared perfectly healthy then the next day it couldnt hold its tail up starting half way down the body and it would only swim a few inches then it wouldrest on the ground. It stopped eating and started losing condition, so i moved it to a quarintine tank and planned on posting n here the next morning but my cat got hungry so i didnt... Now a second kokopu has devoloped the same bent spine.
I do weekly water changes and i dont overfeed.
Any ideas?
Thanks
