I appologize for the lack of pictures.
First, here is the background. S/he is still quite young, about 2"TL so I can't tell the sex yet. Who lives in the 10G tank with the group of Panda Corys and Red Cherry Shrimps. The tank has powerhead with sponge attachment. Which is set at the corner of the tank and water from the outlet is hitting against the side of the glass to create the water current go around the tank.
Anyway, everyday I siphone out some water(about 2~3 gallons) so I can use those water to change the cory fry tanks. I usually tap them up right away but today I was kind of lazy and left the tank with 7G full and 3~4" below the usual water line. Later I went to the tank to see the ABN on the side glass clearly above the water surface by 2",

Times like this make me wish I had some good digi camera and fast comp with big memory.
Sorry no picture but I hope you can imagine the picture and you just have to take my word for it.
But I guess my ABN like the water current from the powerhead very much.
