Did you really think we'd like it better here? There are no decorations to make the fish at home & it looks dirty in there. 2x/month, are you kidding? I do 75% weekly on my tanks & they aren't nearly as crowded as that tank. Overfiltration is nothing... just sweeping dirt under the rug. That is no home for a happy fish...
Edit: Now that I see who posted this, it must be a joke. I don't think that's his tank.
its not just the fish waste, how would you feel if you had to live in a little glass box, they dont have the space to move about, as they would be roaming miles in open rivers in nature. that is equivalent to you living your life in a jail cell. You wouldnt keep a dog in a small metal cage for its life would you?
the fish are beautiful, but they just don't have enough room. even if your water quality is pristine, that still doesn't preempt the fact that they are overcrowded. poor guys...
