Ghost in the Tank

This morning I was up at 4.30, which is the norm, for about half an hour. Due to the box-like nature of my home, it is very rude of me to bring daylight to the fish tank, earlier than necessary, so I simply sat in the dark, thinking about things. I barely notice the small red light inside the tank that indicates that the heater is on, but today it showed me something very interesting. We have two glass catfish in our tank and they hide all day long. You can catch glimpses of them, but they are never out in plain sight. Last night,in the glow of the red heater light, there were my ghost fish. The two of them were swimming together at the top left corner of the tank, all happy and free in the darkness. After noticing them, I started watching the tank, and then I started noticing our plecos sticking to the walls of the tank. As I watched for the half hour, I realized, our tank is a ghost tank. There are two day time fish, but one hides all day. It is almost an entirely nocturnal tank, which makes it seem boring in the day, but eerily peaceful at night. Watching my Ghost tank was quite calming and I got back to bed very quickly, some nights I don't make it back at all. One day I hope to have a good enough camera to take photos in the dark, and will be able to capture and share the serenity my ghost tank affords me.
