What a day this has been so far...
Bendy Harley's strange jerking movements to the left continue, flipping onto his side momentarily and intermittently. As there remain periods of respite when he rests reasonably normally near the surface, almost-but-not-quite drinking from the surface, I've been reluctant to intervene in the aforementioned manner. However, when I opened the tank lid, he zoomed onto the top of the flourishing plant and lay there almost as though he was voluntarily giving himself up to be removed. When I shut the lid, he remained there, watching me throughout the stalks/leaves. He seems to have a more adverse reaction when I'm near the tank than when I observe from afar.
Anyhow, I felt like he was willing me to end his potential suffering - as though he was ready for it (but I wasn't). I took some time to pluck up the courage to do so, by which time I saw him acting somewhat more normally again. In a semi-impulsive moment, I decided to try one last option - set up the QT, put him and both x-rays in it, and then added some API Melafix. I completely appreciate that folk don't rate this highly but felt that a mild intervention of some sort would be less invasive than other medication. There has been no adverse reaction on anyone's part and Bendy Harley may even have improved slightly - calmer, resting more, less frequent episodes of moving jerkily and catapulting.
They'd been in that for several hours when I witnessed Bent-Up Tail X-ray take a bite at Bendy Harley's tail followed by two other bites. I knew I had to separate them, and so decided to put that x-ray back in the main tank, leaving Pop-eyed X-ray and Bendy Harley in the QT - one hovers at the bottom, the other at the top.
Dear knows what the rest of the afternoon and evening has in store...
