I tend to keep the 'inch/fish' rule in the back of my head when I'm stocking, I will admit. When I hit the magic number (according to the rule), I usually slow down. From there, I keep a close eye on my water parameters and look for problems. I overfilter big time usually, so I can handle max stocking or even a little more. (33gallon with aqueon 30 quietflow, Whisper 20-40, Aquatech 5-15) That's over 600gph.
The biggest question we should have is how quickly the water quality dips and how often we have to make water changes. If you are having to do water changes every few days, your probably overstcked. Simple as that.
Plants, overfiltration, frequent water changes are all ways to "push" the limits when it comes to overstocking.
Anyone can say they have good water quality........ despite the overcrowding, especially when they replace 80% of the tank water every second day!
Am I overstocked in my 33 gallon??

Probably not...... but then there is the space each fish needs to feel comfortable..... There's a whole new subject!
