Bruce :

As I have not yet killed a million fish I am not an aquaculturist so these questions may not be applicable. \:D

First at what # x weight will there be to much bio-mass in the Walmart- special chinese aquarium to keep them safely ( a risk level a million killer(like Dr. Frankenbruce) is ok with)? Second should such a Dr. with access to gas , drugs and the like consider adding some antibiotic , salt, slime coat protectant or other aquaculturist concoction to protect his investment? :p ewest
