i have to apologize to jacmyoung and anyone else, after more research, this practice has been done for awhile by many people and not just limited to hong kong/asia but all over and quite a few people have been successful with the lockerroom effect. i still don't agree with it but you can't argue with the success of some people stocking their tanks in this manner.
here is what bob fenner wrote to me regarding this
Hi Bob,
'Chaidan'
As I am planning on my stocking list, I got a chance to see a very
overstocked aquarium from Hong Kong where as many as 10 large angelfish
was crammed inside a 150 gallon aquarium which I thought was cruel and
not acceptable under any circumstances yet I hear it is the norm over
there.
'Is not an uncommon practice...'
Have you heard of this method of fish keeping in Asia?
'Yes, have seen there, and some places in W. Europe and N. America...
mainly amongst folks of Chinese background... and one large service
company on the U.S. eastern seaboard... can be done'
Are the people employing these methods having any long term success
with them?
'At least some of them, yes'
what are you long term mental and physical damage from angelfish being
crammed in an aquarium for an extended period of time and having to
suffer from the lockerroom effect?
'Well-worded... and I don't know exactly. It seems that such an
arrangement might well lead to psychological problems... but the examples I've
witnessed first hand show little signs of such... and often quite
vigorous, colorful specimens...'
I know there is not a guideline of inch per gallon but should even 2
angels be stocked inside a 150 gallon much less 10 or am I overreacting?
'Sort of the situation with semi-compatible mixes of African Great
Lakes Cichlids... either undercrowded, akin to natural presence, or
purposely over-crowded... With commensurate filtration, circulation,
aeration... and feeding...'
Any information would be appreciated.
Thank you,
Chaidan
'Mmm... I wrote a review of a book expounding, exemplifying this
"technique":

By Wayne Shang... You might read it... I am not a fan of this
crowding... as it too often can/does lead to catastrophic loss, but it can be
done. Bob Fenner'
sorry if i offended anyone, especially coolfish china.
