Spinning Glass Fish!

[Milburn95]

Hey!
So my glass fish has suddenly decided to spin round uncontrollably, it’s not upside down like you would expect with swim bladder disease it’s more like rolling over and over. I installed a new light just yesterday, could it be to bright? It just seems coincidental is all, any help would be appreciated, thanks

It is unlikely to be the light, though sudden shock from the light coming on or going off especially in a dark room is perhaps possible. Could more likely be an internal issue, protozoan, etc, or genetic. Which species is this? Some are shoaling and need a group.

It’s a Thai glass catfish and I irresponsibly bought two of them before researching them properly, I now know they likes be together in higher numbers, but the two have seemed happy since getting them a few months back.
