Yes, I have many thoughts on the subject:
1st, captive bred bichirs in general have a higher probability/propensity of gorging themselves to death. For some reason there are individual bichirs that don't know when to stop..... their brains don't register, "enough, i am full". If you observe captive breds vs wild caughts in general, which ones in general look fat/obese?.... it's always captive breds..... super fat delhezis, senegals, endlis, etc.....
Having that said, the above also apply to short bodies, & super short body bichirs..... on top of that, their organs are compacted compared to regular bichirs.... the individuals that aren't brain wired to stop when full, WILL die much easier and quicker than a regular bichir that doesn't know when to stop eating.
In addition, baby bichirs that don't know when to stop eating will also suffer a very quick demise. Out of my 20 plus platinum bichirs, two pieces don't know when to stop eating. The two have been seperated and only fed what is needed. Those are probably destined to be individual pieces in other tanks..... if allowed to stay with the others.... those two would die without a question.
So IMO about ssb endlis and sb endlis..... the problem/death occurs when it is fed when food HAS NOT fully digested from the PREVIOUS feeding. A full stomach itself is harmless as long as it is allowed to fully digest it's food before the next feeding. Now if the ssb or sb endli doesn't know when to stop eating, they must be fed proportioned feedings at every feeding.
I have heard some say, BIG EATERS die younger. True. But why?...... because they are fed/eat while the food from the previous feeding has not digested properly.....they die a slow death.... Also, bichirs that GORGE will definitely have a very shortened life UNLESS removed and put in a tank where feedings/amounts are regulated.
Hope this helps and hope it makes sense.
