Now for the dissection.

Having dissected fishes myself - not for diagnostic purposes - I would not assume the swollen organ to be the swim bladder, but the intestines. Apparently inflated.

The internal cavity of a fish is a bony box, with iver, intestines and so in inside it. If you take this out, there is a few things on top of the bony box, namely the kidneys (shaped way different then ours) the gonads and the swim bladder.

In some fishes, the swim bladder is encasulated in a bony contruction, I'm not certain whether this is the case in Loricarids. But regardless this, the swim bladder is not in the bony box you've shown

Inflated, empty intestines - that could spell disaster for the fish: Something went wrong with the digestive system. At least, that would be my guess.

Thanks Bas, interesting information. Despite showing slight signs of the crud on their skin/scales again, the fish are eating very well, and a lot more active for it, they also now appear to have normal colouration, before they were pale.

My main concern is the pale gills at the moment. I'm hoping that the crud/pale gills is them getting used to clean, non medicated water again, and as they are eating it'll help them get over it.
