I was hoping for some answers here, I have a couple of big yoyos and I've noticed their size go up and down every few months. I always assumed it was eggs, and the big ones were the female ones (clarification, I have/had 5 yoyos and only three of them get super big, currently there are 2 that I would consider to be huge). To be clear they aren't as big as the one in the original post but it also doesn't seem to just be a large gut attached to a slim fish, it seems more rounded over all. Anyway to get to the point I have just found the biggest fattest one dead. She was fine yesterday and no signs of illness and I didn't notice her body when I fed the tank earlier this afternoon but went back to check some fry and saw her there. She has been dead a little while as she is stiff and she's left a mess of slime where she lay - certainly not as bad as a yoyo I lost last year who started shedding slime, losing colour and was gone in 48 hours. I saw two others doing the same, panicked thinking it was columnaris and salted the tank and while it killed most of my plants it did seem to save the fish as they recovered and I had no further losses.
This time I am at a total loss, unless she's fat because she's full of worms maybe? I was planning to do a big water change tonight anyway, the tank is 5 foot/450 lt with other fish all seeming healthy apart from a few geriatric peacock gudgeons who look a bit wasted/slim. I've had these fish since mid 2017 and they've been in this big tank for a couple of years now so for one of them to just drop dead is really puzzling.
