Perhaps my fish purchasing practices are different or maybe just my hobby
set up for I only have one large tank and do not change my stock often. In
fact, the most tanks I've had running at a time was only 4 and that was for
a short period of time.
As for what I expect in a death rate when purchasing new fish... Zero. In
defense to this I must say that I have not had a system that focused on
large numbers of small fish such as tetras. I have kept numbers of some
smaller fish as high as 9 but I only built up to that level in fear of
overloading the biofilter and mini-cycling the tank to dangerous levels.
My purchases consist mostly of 4 or less fish at any given time and I
currently only have a stock limit of 18 fish in my 240gal. With this, I
feel that an expected death rate of zero is reasonable. This is not to say
that I have not had any deaths, just that the expectation is complete
survival.
