My 5ish year old African muttly just passed this evening. Fish was increasingly "obese" looking over the last year. 4 days ago, took on a more bloated appearance, stopped eating and became lethargic. Was going to put him out of his misery this weekend (past efforts to treat for everything from Malawi bloat to overeating were unsuccessful).

Anyways, I can't find any helpful (read--with pictures) guide on what I should have been looking for during an autopsy. So I did my best and took as many pics as I could with nobody to assist during the process. Please can someone look at these and tell me what I'm looking at. I have my ideas, but because the fish's insides were not the norm, I cannot for sure identify everything. More questions and explanations with the pics.

Upon initial incision, all bloating deflated in a rush of blood and fluids. Internal hemorrhaging I think, caused by what though? Not exactly sure.

After removal of hard organ located in the area of vent (consistancy and hardness close to hard boiled egg yolk, maybe harder). What concerns me here is what I think is a very large, very black liver beginning to show and what I think is the stomach just below it.

Closer inspection of hard mass. I have cut it open here after inspecting it for ruptures and found none.

Backside of hard organ. Note thickened white area.

Chopstick pointing to what I think is the stomach. What this says to me is that the hard mass was not the stomach but his intestines having been distended/impacted. Am I thinking right? Note the large dark organ, is this the liver? Lots of fatty globs on it too.

The rest are just more views of the various organs arranged differently. A kidney is found up front in one shot. I have amature ideas on what could have happened here, but would like to hear what you all think before I put ideas out there.

Almost looks to me that he had some sort of impaction.
 
@blacktarotannin- The fish was male as far as I've ever known from behavior during attempted spawns with one of my L. Fuelleborni females. In the autopsy I could not find or clearly identify gonads of either sex.

@just prince- No, that is the hard impacted mass cut open and placed on a standard sized barcode for reference. The insides of the mass looked like a conglomeration of fatty yellow globs, egglike clear globs and hardened but pasty pinkish "poop".

@pharoah- My opinion is the same as well. What really gets me is that this fish functioned just fine for years (3+) with a milder form of this bloating. Could he really have taken this road that slowly? If so, what a trooper he was and how terrible I feel.

Does the liver seem odd to anyone else? The only comparison I have to a healthy fish is from a blue mackerel dissection on an Australian uni website...they state that a saltwater fish's liver is smaller than a freshwater fish's (and why) but say nothing of color for freshwater.
 
Necropsy,
and the object you removed in my opinion more closely resembles a tumor as opposed to impaction from a substrate. The way you are describing how the organs feel to the touch is consistent with what a tumor feels like if you ever have the opportunity to hold a few.
Internal tumors can be advanced and beyond repair before the fish shows any symptoms, such as that distended abdomen. If you attempt another necropsy avoid cutting into the abdominal cavity, finish the cut before the anal fin, and pin him.
