I've received the final pathology report on Keybo, so here is the third and final part on what happened to him. This will get a bit graphic, so I'm warning you.
Keybo died on June 18, 2007. As I've reported previously, he had been slowing down and behaving differently, and he had the whole
funky thing going on with his eye. I had been taking photos of the fish, trying to get a good look at what was going on with Keybo, but he was the hardest to capture, until I turned off the pump for a few minutes on June 15 and captured some good images of the fish in relatively still water. Yet, what I wasn't seeing was what was happening to Keybo.
As sick or "not himself" as Keybo had been, I hardly suspected that I would be finding him lying on the pond on Monday morning. I don't remember which side he was lying on, and while I made a quick trip to the grocery store to buy a bag of ice, my wife got him out of the pond. I really wished she hadn't done that though.

What I missed from the photos on the previous Friday was that Keybo was simply rotting away from the inside. It was very obvious when I saw the right side of his face, especially the lower part beneath the eye I had been paying so much attention to. In the curvature of his face in the water, I had missed that his face was wasting away.
It took a while to figure out what to do, but I wanted to know what killed Keybo, and to get some idea of what Dreamcicle and Blue might be facing, if it was contagious. Normally we would just bury a fish somewhere in the garden.
I ended up taking Keybo in for a Necropsy at the
C.E. Kord Animal Disease Laboratory in Nashville, TN. It's part of the Tennessee Department of Agriculture. There I met Dr. Edward R. McKinley, a Veterinarian. Dr. McKinley was very patient with me and allowed me to give him some long and extensive background on the history of the Buddha Pond, its residents and the specifics of what had been going on with Keybo.
The diagnosis is in: Keybo died of
Hemorrhagic Septicemia. His body was full of a bacteria known as
Aeromonas Hydrophila. Whatever had been going on with right eye had extended right into the skeletal muscles of that same side of his head. No significant lesions were found in his heart, intestines, pancreas or gills. There were mildly inflamed cells in his liver, kidneys and spleen.
Bacterial cultures had been made from samples of his liver, a lung, his eye and gills. CFU is the measure of Colony Forming Units of, in this case, the
Aeromonas Hydrophila. The breakdown looked like this:
Liver - 50 CFU
Lung - 50 CFU
Eye - 100 CFU
Gill - 100 CFU
From what I read,
Aeromonas Hydrophila is common in fresh water. It can infect humans as well as fish. It's very aggressive once it takes hold, but it needs some way to get an upper hand, such as a wound or an otherwise impaired immune system.
Keybo did have those nasty wounds. The ones that made me wonder—facetiously, of course—if he used to sneak out of the pond and get into bar fights. Otherwise, I don't understand why Keybo's immune system would have been compromised, at least not any more so than the other two fish in the pond.
Now I'm concerned about Dreamcicle and Blue. Dreamcicle in particular. She does not look in to be ill in any way. The only difference in her that I've detected since Keybo's death is behavior. It's been all over the map, though, until recently. When Keybo was first gone she spent a day or two fussing about the pond, as though she was inspecting it and trying to find out where he had gone.
We have plant baskets in the pond, though there was nothing in them yet when this happened. She kept trying to get behind them, and at one point she got herself stuck on top of one of them. Fortunately it happened while I was around to see it and rescue her. But for days now she has hardly been herself. She just sort of hangs in the pond. She'll pick a spot and just hang there for a long time.
When Keybo started isolating himself it was easy to notice. Keybo generally cruised around the pond on his own and/or was more or less forced into frolicking with Dreamcicle as she tended to pay a lot of attention to Keybo, almost like she was nagging him half the time. When he started avoiding the other two fish, hanging out in "corners" of the pond, and when he stopped swimming away from me when I approached the pond (he was a scaredy-cat), those were all such obvious changes that I couldn't help but to notice.
With Keybo gone, it's difficult to say what Dreamcicle's normal behavior should be, without him around. I have to confess I don't know all that much about Blue. That's mostly because he is so hard to see and therefore so easy to ignore, other than at feeding time (which is a change in itself, this year). With only two fish left I've paid more attention to him lately. Blue seems to hang nearby and show some kind of deference towards Dreamcicle. Otherwise he goes for slow cruises around the pond, like a stealthy submarine.
Meanwhile, however, Dreamcicle is doing a lot more idle "hanging" than I've ever seen her do. While I don't know her to be a "bottom feeder" per se, she has always seem to enjoy "grazing" from the bottom of the pond. It's common to find tiny
Bloodworms down there, and they are the larvae of Midge flies, and we have those, too. So I don't often panic when she seems to ignore fish food, because I imagine she's already found herself plenty to eat.
But because of Keybo dying from this horrible bacteria that rotted him away from the inside, I'm concerned now about both of the fish, because Dreamcicle is acting different and Blue is nearly impossible to inspect for sores, because of his color. I've put some MediKoi into the pond, which is supposed to be a rich food which contains anti-bacterial medicine, but Dreamcicle doesn't seem to be eating it. It's difficult to tell because it sinks to the bottom of the pond. Their usual food floats.
It's driving me nuts, that's for sure. I don't want to lose any more fish.
I miss Keybo. He was kind of ugly, but it was fun watching him and Dreamcicle. He got so big and by all measures that meant I had an overcrowded pond. But everything seems out of balance now. Three fish seems like such a good number to have.
