Thought I'd post some vids of my unusual tank. Yes, it is overstocked. I bought all these fish as babies when I set up the tank in 2007 and haven't purchased a single fish since. The most unusual part of my tank is the variety of fish which breaks the "rules" of much fish keeping advice. I have tiny fish an inch long hanging boldly with fish 6, 7 even 11 inches long. A few oddballs in there as well. Also, many of the fish are, (in just little over a year), larger than most books say the max size is. Finally, click in the last link for a shot of one of the most amazing eartheater cichlids I have ever seen.

Many more on my youtube page.

Those are some beautiful fish, for sure.  I am quite surprised that you have not had a lot of aggression and dead/eaten fish. 

How often do you change the water in your tank?  I would imagine that keeping clean water with that many fish in a tank that size is a challenge.

Me too!

I try to change about 65% every 2 weeks
