How am I a troll if thousands of people are doing this in China. I grew up in Hong Kong so I owned one of these tanks before and know a lot of people that do this.
How can you tell if your fish are happy or not? I have a friend that kept an angelfish tank for 10 years with no loss. I know a lot of people in China that have successfully kept this kind of tank for more than 20 years.
This is how you overstock your FOWLR/FOT
1. Put very minimum rocks to no rocks. For example, a 20 gallon tank you can put max of 10 lbs of rocks. This is to ensure the swimming space of the fish.
2.Put lots of ceramic rings/live rock rubble/biofilter media/etc. This is to be sure...
