Unfortunately, today appears to be the day that Trixie passed away. I called the place where I received her from via shipment to simply ask if any other fish in the batch had experienced similar issues, they had not.
After asking around, it seems nobody has ever seen or even heard of anything like what I experienced with Trixie. Therefore, I figure I should at least add this strange ailment to this database in case anybody else does experience similar symptoms.
Trixies Disease
Symptoms:
- Seperation from the pack
Inability to gain weight
Lower -but still existent- appetite
Chronic Shaking
- None known as of 7/9/19
I believe that the ailment was probably neurological due to the failure of the medications. Although the symptoms seemed reminiscent of IPs, the failed treatment along with the chronic shaking suggest that IPs were not present.
I hope this information helps others in the future, perhaps alternative treatments may have helped.
