Got 2 spotted danios (possibly a pair) 2 weeks ago. They seemed fine and were happily swimming fast all over the tank. Did 50% water change this morning and immediately noticed danio looking very strange:
- Has humpback deformity on spine - I never noticed it before, back like an arch instead of straight.
- Tail twisted to one side so whole body is curved
- Swimming oddly, partly on side , probably because of curved spine and twisted tail.
He wasn't like this when I got him and seemed OK yesterday. Is it the water change?Other danio and small jewel cichid I added yeserday seem OK. Water was dechlorinated and temp of new water similar, perhaps slightly warmer.
Looks bad. What can I do to help him? Is it contagious to other fish?
