200= about 52Gallon?
Meaning you can keep about 52 inches of fish in your tank(not the best rule either)
12 neons - about 12Inches, 4 zebs - about 5-6Inches
4 rummy nose -about 6Inches, 4 glass blood fins- about 4Inches
2 red honey gourami - about 4Inches, 2 golden honey gourami, about 4 Inches
4 harlquins,about 4Inches, 1 male red dwarf gourami about 2 Inches
1 cobalt blue gourami about 2 Inches, , pair of bristlenose plecos about 8-10 Inches Already thats about 50-55Inches
and theres still a good aleast 50Inches worth of fish below :-?
SO even though the rule you are going by isnt the greatest, you are still going way over the 'limit'
