There was a comment earlier on this thread that the only solution was to "agree to disagree". You are wrong. This debate is always made between the experienced and the inexperienced. The only way you can maintain a tank in the Japanese style is to know everything you are doing very well. While most overstocking rules are great for aquariacentral...it basically ends there...these are are rules made for BEGINNERS until you know how to handle your fish. Our hobby I can assure you is not about keeping fish, but keeping water. Once you have mastered that the fish will be fine. Check this tank out...im pretty sure he is a member here...

A lot of hobbyist can't even keep a motoro ray alive for long periods...this guy has tigrinus, Tiger rays, etc....whatever your argument....the tank speaks for itself...
