Wow!!! I never realized I had 48, um I mean 49 (just realized there is an upside down cat in there, too) critters in that tank. With the plants, and the diverse swimming areas, it really doesn't seem that full. I guess you could say I am a little overstocked, but I keep up with my water changes and my tests always come out great. The dual Quietflow 30 filters help a lot giving me 400gph total turnover.
