Hi

I have a few cories showing symptoms of shivering/twitching for 3 seconds (body contorts as well during this time). I've not been able to find such descriptions on the internet or the disease related web sites.

[Other than that, some flicking from the affected fish but no other external symptoms. Going on for 3 weeks now and they are still eating well].

Keen to hear if anyone else seen the twitching symptoms before as I can't find it described anywhere.

does your cory roll the tail to the side sometimes, just like it would like to see the back of the tail?

Yes, that's a good way to describe it.

Do the Corys scrape their gill plates on the substrate?

I dont see my cories doing that? But sand do stick on their gill plates!

There is no way of knowing that the reason is the same, but I lost all cory Juliis that did roll the tail to the side. Than they were motionless for most of the day and eventually lost balance and died. I lost 6 out of 10, the remaining 4 are healthy. I could not pin point the problem, it looked like some sort of parasite, also I treated for bacterial and parasite not knowing what it is. There is a thread about it on this forum somewhere, I posted it to try to get some help. I could not cure any of them. Again, there is no way of knowing that yours have the same problem.

Those that show the symptom did scrape on the bottom. I've moved them from a smaller 10G quarantine tank to a 30 G tank just to be sure the water quality is better although I don't think it is due to water.

If it is due to parasites, I could not see any external symptoms. Dosing Interpet #7 is an option.
