would placing too many fishes all at once in an est. tank cause death in ur tank? base on my knowledge, and this is from reading you should not. 2" for every 5 gal. is the rule. to let the current bio load adjust to the added fish. So is a bio shock is when all its parameters spike up or can a lack of Oxygen be a cause. will it show on your h2o tests. and how long will it last b 4 it stablize.
i think its just plain O stress that kills newly added fish.

It could if your biological filter is not developed enough to keep up with the waste those fish produce. Don't forget - fish also urinate.
It is suggested that you only add about 1 fish every couple of weeks so that the bacteria population can increase as the waste from that fish is added.

There is no rule about 2" per whatever gallons...you can't compare 2" of a tang to 2" of a jawfish - MASS has way more to do with it, common sense is the only rule you can use :)

Oxygen - I highly doubt it. If you are running a skimmer and have good gas exchange at the waters surface, that should be a total non-issue.

Regarding stress - there are so many variables on this- was the fish newly arrived at the store after a weeks journey from half way around the planet...how long had it been since it was last fed during that journey...did you stress it bringing it home in an uninsulated bag and the temp dropped...are your tank parameters not up to snuff...are your tank parameters fine , but not for the type of fish you purchased...is your tank the appropriate size for the fish...does the fish like low lighting and you have MH...what tankmates are you putting it in a tank with, are they compatible...too many variables as I said...

you dont want to add to much at once because that could shock the tank by putting too much in at once adding more waste with not enough bacteria to break it down.

in the past ive placed atleast 3 to 4 at a time and never had a problem. it was this past week i put more than that, and 2 i notice didnt respond well. the rest were swimming eating playing etc. By day one 2 died, ive tested the h2o, normal. day 3, 1 more dead and now evryone is still good and let me mention it was only the new arrivals. next time ill take it slower but it never happen to me b 4.

u got a long way too go bro... good luck!!!

imo a bio load shock is when too many fish or corals are introduced at the same time.. u can reduce this shock with Dr. Tims nitrifying bacteria... or any type of nytriflying bacteria.... good luck!!!

try a nitrate test to see if the nitrates spike...
