Friends VFSR suddenly died.

[Squid]

My friends VFSR suddenly died.
what could be the cause? was told that water change was done at around 4PM, with anti chlorine , the VFSR was fed at around 12 Pm noon , diet is mainly MP fed 3 times a week.

water change is once every 2 weeks , 30%

what could have happened? was told at 8pm it ate some mp again, then around10:30 Pm it suddenly lost balance and turned belly up.




when they opened up the stomach , it was full of eggs.
what could have been the cause of death?

Normally yes

i've seen quite a few posts on dystocia / egg bound deaths so let me share this useful information from one of the threads at http://www.koiphen.com. while the below quote involves koi, it should be applicable to aros as well.

Our observations have led me to some conclusions that seem to be backed up by other peoples experiences as well. Important among these is the need for the females appetite to go down so that her body will NEED to re-absorb the eggs naturally. An egg laden female that doesn't spawn but continues to eat normally will do 3 things with the food she consumes.
#1 She will use it to supply energy for swimming and osmoregulation.
#2 She will use it to store energy and grow.
#3 She will use it to produce more eggs.
That is what they are programmed to do under normal circumstances and the fact that their ovum is filled with eggs already won't prevent it from happening anyway. In the process several things happen that can cause death by impaction. Fat stores will create a blockage that prevents the evacuation of eggs under any circumstances. Having become egg bound the old eggs will be subject to decay in utero. The blockage of the vent area becomes exaggerated to the point of interfering with evacuating waste, further compromising the health of the Koi which leads to problems in the gut that spread throughout the body of the Koi resulting in death.

so overfeeding is also an issue, although it shouldnt be in your friends case since he only feeds thrice a week. another article i read from chinese forums was if u had bad water quality it could cause eggs to impact and rot. not sure how true that is, but i assume it's possible since bad water quality = low immune system = aro is left susceptible to all sorts of diseases that a normally healthy aro is immune to... and bad water + egg bound aro = very weak / low immunity aro.

on a side note, after moving my bigger red to new tank (n keeping her in a bag for 6 hours through the process), she stopped eating for more than a week... almost 2 weeks now. yet i noticed she was still passing out shit... which was a lot more greenish than normal. so i can only assume i was right in sexing my aro, and she's not eating coz of digesting the eggs.

thanks really appreciate the feedback.
I'm thinking aros need to be starved a period of time specially big ones.

On the same day feed at 12pm and change water at 4pm?

[gtohow]

water ph swing dramatically with heavy feeding.
so questions how much feeding and how much time digesting then?

water at the wrong time?

[Squid]

thanks, yes same day feeding
I dont know how much was fed, i think feed 100 % full if im not mistaken

it'll take a LOT of feeding to change the ph much in a short time... for instance i feed around 1kg of food at one go and the ph drops by 0.1-0.3 over the course of a few hours.. and i dont have much buffers.

Yes, that is what I think too. Sometime I just wc after feeding... So is it a thing to avoid, to feed and wc on the same day? Any theory or reason to support other than the pH issue?

Possibility of egg sac burst in stomach ?

Choked due to heavy feeding ?

Interesting case of sudden Aro death. will be a great source of info if the cause(s) is(are) establish.
