When looking at other people's tanks...
I love to look at other people's fish tanks. The great majority of them are awesome and so much better than mine, but once in a while, I see stuff that make me go, "Why??". Nothing big, just little pet peeves like:
1. A low water level for no reason, like 2 to 5 inches below the edge of the tank. I'm all like, "Why you no fill tank up all the way to the top???"
2. No background. My brain be like, "Why you no put background?! Why you like looking at filter and cords and ugly wall behind tank??"
3. One tetra. "Why you no give him buddies??"
What are your pet peeves about other people's tanks (or your own)?
